By the turn of the 21st century, two parallel processes occurred that led to the proliferation of gasification technology. The first process was an increasing acceptance of the climate change and a desire to reverse the negative impact of it. The second process was the constant rise of crude oil price. These needs demanded an alternative that would be both climate friendly as well as cost effective. The answer, of course, was gasification technology.
The gasification process involves heating of biomass at very high temperatures of more than 700° Celsius without sufficient air. This process makes the combustion incomplete and leads to the production of different fuel gases like hydrogen, carbon monoxide, carbon dioxide, and others. The produced gases are collectively called syngas, and they are combustible and act as an excellent source o f renewable source of energy.
In the past gasification technology was used as an internal combustion engine for automobiles, however, in the modern time, the primary purpose of gasification technology has been limited to heating. To fulfill this, primarily wood gasification boiler is used.
Wood gasification boiler is advantageous over conventional boiler in many respects.
- They are highly efficient as compared to other heating systems.
- This technology is very simple to use.
- The produced syngas is very clean, as very less soot is produced and this makes the maintenance and cleaning of the boiler a less frequent occurrence.
- Wood gasification boilers emit very low amount of particulate matter. This reduces the need for air filtering systems that are so necessary for other heating systems.
- The carbon footprint of these boilers is very less. So it has the added advantage of being climate friendly.
As with all other things, even wood gasification boilers have some disadvantages. One of the biggest disadvantages is its large size. This also makes this technology less mobile and thus adding to its disadvantage. The process involves heating wood at high temperatures and hence takes some amount of time at the beginning of its operation. However, this disadvantage has been eliminated by introducing programmable circuit, which enables the user to start sometime before the required time. The gasification of wood produces a substance called wood tar, and its cleaning requires a dedicated water treatment. Anyhow, despite these disadvantages, people have gladly accepted this technology as one of their primary source of heating needs; this is evident from the increasing popularity of wood gasification boilers in Australia and also in other parts of the world.
Due to the increasing popularity of wood gasification in Australia, a large number of different services have originated that takes care of all your heating needs.
Kroll Heaters Australia is the answer of all your heating requirements. They specialize in providing hydronic heating, which operates on gasification technology and has multitude of features to enhance your comfort. All products of Kroll are made from high quality materials that are expected to work at their full efficiency.

The wood heating has already made comeback for a few years now. This is not surprising given that it is an economical and ecological solution. High-performance wood-burning heating systems are available in a wide range of models, from stoves to boilers. Such is the case with the wood-fired boiler.
Wood: a fuel with many qualities
The firewood is a very advantageous fuel since its use and its acquisition will pose you no problem. In addition to its natural and ecological appearance, it can achieve significant savings. Indeed, it costs less than any other energy source such as gas, fuel oil or electricity. In addition, it can be in various forms: wood-logs, wood pellets, forest chips and shredded wood.
How does a wood boiler work?
The operating principle of a wood-fired boiler remains the same, regardless of the fuel used. Thus, burning wood produces energy that is used to produce hot water for housing purposes. On the one hand, there is the hot water of your heating network that feeds the radiators of your home or your floor heating. On the other hand, it contributes to the production of domestic hot water for the needs of the bathroom and the kitchen.
What are the different types of wood boiler?
There are three models of wood-fired boilers: the wood-log boiler, the pellet boiler and the shredded wood boiler Australia.
In the first place, the log boiler is the most affordable model. Small volume, it is very easy to use. For its performance, it can reach up to 85%.
Secondly, the pellet boiler is the most efficient model with a thermal efficiency between 85 and 95%. Moreover, it is very quiet equipment that offers a comfort of use of the most pleasant. This installation also has a very long autonomy which can be up to several months. Like the pellet stove, it is equipped with a tank that ensures its automatic feeding.
Finally, the boiler with shredded wood or with wood chips also offers a very exceptional yield which can be between 75 and 90%. Like the pellet boiler, it incorporates a silo for a better autonomy.
Some information about choosing firewood
The performance of your heating appliance depends very much on the characteristics of the fuel you are using. Use the following tips to choose your wood.
Wood species are classified into two major families according to their density:
- Hardwoods (oak, beech, ash, chestnut, charm, walnut, fruit trees, etc.)
- Coniferous and softwoods (spruce, fir, pine, larch, poplar, willow, etc.)
Hardwood hardwoods are the most popular for domestic heating, with the exception of the chestnut tree which bursts on burning. Soft and resinous hardwoods burn faster! If they are poorly stored, they degrade rapidly. Softwoods are nevertheless appreciated for their rapid rise in temperature.
Wet wood burning is not recommended for various reasons:
- Environmental issues: the burning of “green” wood releases many pollutants;
- Economic: a damp wood provides about half as much energy as a dried wood;
- Practical: high-performance appliances will not reach their rated power with fresh wood. The material will get dirty faster and may deteriorate.

Biomass boilers need a silo for bio fuel storage located near the boiler. From it, an endless screw or suction feeder, takes it to the boiler, where the combustion takes place. The fuel must be stored at an inclination of about 45 ° for proper insertion into the boiler.
The combustion chamber is the whole area where combustion takes place in a boiler, and in which three parts can be clearly distinguished:
The first is the area where the fuel is mixed with the primary air and, by means of a partial combustion, the biomass is gasified, that is, it is transformed into a combustible gas. In the case of stoves or gasification boiler of efflorescence (load from below) would be equivalent to the crucible, in burners would be the fixed grid and in large boilers the mobile grid.
The second is the area where you can clearly see a flame and where the secondary air usually enters.
And finally, the third composed by the rest of the chamber where there is no visible flame. This part continues to produce combustion, but the oxidation concentration is low and invisible to the naked eye, although it is a key area for the reduction of CO and unburned. In some chambers, this space is separated and then called the post-combustion chamber.
As a general rule, the combustion chambers have an optimum working temperature range between 600 and 900°C. Below that temperature, the unburned and CO increase very clearly. On the contrary, above that temperature, NO levels are triggered by oxidation of the nitrogen in the air, and also cause the need to use more resistant and expensive materials in the construction of the chambers.
The temperature of the flame depends on the moisture, density and calorific value of the material to be burnt, which causes it to be much higher or much lower.
The heat generated during this combustion (in this case of natural fuel) is transmitted to the water circuit in the exchanger built into the boiler. The hot water generated is used for heating and sanitary hot water, air conditioning of swimming pools, etc. The heating can be by any of the conventional water systems, for example, under floor heating, radiators or fan coils.
Advanced models include switching on and cleaning the automatic heat exchangers as well as automatic extraction and compression of the ash so they have to be removed a few times a year. Some manufacturers even offer to monitor and control the operation of the boiler.
When burning biomass some ash is produced, which is usually collected automatically in an ashtray that must be emptied about four times a year. The amount generated depends mainly on the fuel used and the power of the gasification boiler.
To optimize the operation of the biomass boiler, we can install an accumulator (depending on the use of the boiler and the manufacturer), which will store the heat in a similar way to a solar energy system.
As you see, they require many more elements than a fossil fuel boiler, and here we have not named many of them. It is therefore logical that they are more expensive, but the price of solid biofuel, much cheaper than conventional fossil fuels will make you recover the initial investment very soon.

Wood pellets have been used for years to burn stove, but they are now also used for generating required heat in homes and offices.
This is done with the help of wood pellet boilers – the boilers in which wood pellets are used for producing heat. These serve as a central heating system.
How does it work?
Wood pellets are stored in a different area than the room in which boiler is located. Different ways are available to convey the pellets from the storage facility to the boiler room. There are different techniques for combustion in these boilers.
Systems:
These boilers are used with one of the following systems:
- Hot Water radiant system i.e. hydronic system
- Hydro-air system
- Forced hot air system
- Baseboard
Pros:
- The level of convenience and comfort with a wood pellet boiler is same as the conventional boilers which use fossil fuels.
- Pellets are not bulky, unlike firewood, and hence are easy to use.
- Wood pellets are easily available.
- Wood pellets are cheaper than fossil fuels, thereby making this system the economical option.
- Pellets are a renewable and carbon-neutral fuel source.
Cons:
- The pellet oven in these boilers, warm up slowly, which decreases their fuel efficiency.
- These boilers are less convenient than oil or gas boiling systems.
- In some cases, the efficiency is affected negatively if the boiler operates with partial load.
Key facts:
- The system regulates the fuel input so as to match the required heat output.
- To improve efficiency and decrease pollution, pellet boilers of latest technology control combustion either via a temperature or flame space sensor along with a suck-blow fan.
- It is very necessary to keep the pellets dry as even slightly wet pellets can affect the efficiency of the boilers.
These boilers can be used either as a stand-alone heat source or as a primary heat source supported by a secondary boiler serving as a backup or even as a supplementary heat source.
Thus, wood pellet boilers have proved to be the energy-efficient, environment-friendly and cost-effective for fulfilling heating needs of the people.
