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.

If you are an eco-friendly person and want to use the most convenient method of wood heating then your prominent choice must be “wood gasification boiler”. As wood is considered as the renewable source it guarantees the unlimited supply of sustainable energy.
Wood gasification boiler – its true significance!
Central heating is done with the help of wood. Yes, you heard it right; some wood boilers are automated, especially for regulation of air combustion. They are not self-igniting, as you would discover with pellet boilers and fossil fuel boilers and heaters. Commonly, wood is sustained to the boiler on more than one occasion a day during the heating season. In this perfect world, the boiler is fired extremely hot to get the best productivity, limiting unburned gasses, and residue and creosote development from cooler fires.
Since the boiler generally gets hot generally quickly, the heat is moved to an accumulator, where it is drawn off throughout the day as required. Provisions must be made for a heat dump, for times when an excess of heat is created for the system to securely carry.
Reasons why wood boiler is so much popular?
- They’re energy proficient: Wood boilers accessible in Australia usually work above 75% energy productivity so you’re getting the most out of your money.
- Wood boilers are carbon independent: Wood boilers are carbon independent. The wood that is burnt to fuel boilers only discharges carbon dioxide that it has beforehand absorbed from the atmosphere – making it a perfect energy source that represents no hazard to the earth and diminishes your carbon impression as well!
- Save cash on your energy bills. Wood boilers can keep running on biomass pellets, wood chips or logs, each of which differs in cost – yet all are less expensive than gas and electricity!
- Effectively control the amount of energy you’re utilizing. With a wood gasification boiler, it’s easy to measure how much fuel you’re using. Numerous frameworks can be controlled through your cell phone or tablet as well – so you can turn your heating on before you’re home without depending on clocks.
- Wood boiler make your premises free. With the help of wood boiler you are viably making your own particular energy, but only you have to depend on wood providers – though when you utilize gas or power to warm your house but in that you’re helpless before the energy organizations and their regularly growing expenses.
- Set up your home for your upcoming future. Your move towards renewable energy means you will save one more day of your life – so, why not make it within the near future, as it is sooner than later?
- Benefit from the Renewable Heat Incentive. The Renewable Heat Incentive is a government supported plan that gives yearly installments to individuals that are utilizing renewable energy to heat their home or business. The installments keep going for a long time and more than it takes care of the expense of the boiler in any case!

Across the world, home heating and energy requirements are growing, and people need more innovative solutions. While solar energy is often considered the Holy Grail of reusable energy, in many ways the solar panels can only provide you a fraction of the energy you need. A solar installation may power your television, computer, refrigerator, and other household appliances – but home heating requires significantly more energy than the solar set up can provide! This is where people require more economic solutions which can use different energy resources.
A wood gasification boiler is not new technology in any way, and this system has been in use for more than a century. However, till date, very few alternatives can provide you complete home heating solutions as affordably as this well trusted system. Using various kinds of fuel resources, gasification is an economic way to power your home heating system. While people may think that burning wood is not exactly ecologically friendly, gasification does not require high grade timber. In fact, any kind of biomass can be used to provide home heating.
Wood gasification boilers can convert wood chips, pellets, coal, biomass, and a variety of other fuels to energy at minimum cost. The system is simple, as the fuel is burnt in a limited oxygen environment to produce wood gas. By sealing in the wood gas, and combusting it in a high oxygen environment, the gasification system can convert any source of fuel into an effective heating system for your home, or even your swimming pool! Over the years, companies have developed this kind of boiler to be more efficient and reliable. The latest boilers in the market ensure the most efficient fuel utilization possible.
This kind of heating system is most effective for large homes which require a lot of energy to heat. If you use traditional room heaters, you would be spending a huge sum on your regular electricity bills. The gasification boilers provide you sustained heating at low costs as it consumes little electricity to start generating the wood gas. Once the wood gas is produced using the alternative fuel source, it can heat water quickly. This heated water is then stored in accumulator tank which circulates the heated water throughout the house. The excess heated water is kept in an insulated environment for further use as required.
The biomass used for combustion in such wood gasification boilers may be a combination of fuel resources. If you live in an area where wood is easily available, you don’t need to worry about keeping your home heating system running. If you don’t have a constant supply of wood scraps, you can use coal or wood pellets which are low cost alternatives. The versatile types of fuels you can use is what makes these boilers ecologically friendly as well as cost effective!
The most important factor about installing such a wood gasification boiler system is to ensure that you have the right vendor. These home heating solutions include a number of systems like the boiler, pump, accumulator tanks, and piping. While you may think that the set up is expensive, if you consider the many benefits in the long run – there is no better alternative. While it is important to make sure that the system is cleaned and maintained, wood gasification is a way to reduce your energy costs to a fraction and save immensely on your electricity bills.
