Centuries old technology
The technology is certainly centuries old.
Probably our grandmas used the basics while cooking
all the time unaware of it. 
What certainly matters is that Gassifier technology and Gasification
Boilers are one way to cut down your heating and hot
water bills this winter because they can be as efficient as up to 95% using freely available and economical biomass fuels.
Gasification and Gasifiers
Gasification boilers use biomass as the primary fuel, the main aim being to produce Producer gas which is a mixture of several
energy rich combustible gases.
The Biomass used covers a wide range of solid fuels such as firewood, corncobs with kernels,
paddy husk, and wheat straw,
wood pellets or even municipal garbage.
The list is not exhaustive!
History of Producer gas
Gasification technology has been first discovered around 1839 and is credited to Bischof.
The resultant gaseous fuel of gasification was called Producer gas.
Use of the more common fossil fuels coal and coke for this process was the order of the day rather than biomass in those times.
This new discovery helped to give momentum to the industrial revolution, creation of new wealth and the further improvement to human living standards.
Use of gas for domestic lighting, street lighting, cooking, smelting, early electrical power generation, automobiles etc. were direct out comes
and utility enterprises made good money with it till about 1930 when cheap (at that time!) natural gas replaced it.
Gasification Boilers
Gasification technology has been well adopted to produce the heat necessary for the functioning of boilers which
exhibit outstanding fuel efficiency.
The Composition of Producer gas typically consists of approximately 18% Hydrogen Gas, 03% Methane Gas and 22%
Carbon Monoxide gas as the most economically important products. All of these are excellent fuels.
Use of this mixture as fuel in your boiler would result in clean flames, high energy efficiencies and minimum residue.
Major Components of a Gasification boiler
A packaged gasification boiler essentially consists of;
- Fuel feeding Hopper
- Feeding augers
- A Loading /Burning Chamber (Ceramic Lined)
- Burner/Gasification chamber (Ceramic Lined)
- Heat Exchanger and water jacket
- Ceramic lined nozzles
- Flue gas vent
- Electrical Blower
and,
The Processes of gasification in the Boiler
The Hopper at the top is fed with wood pellets or in the alternative suitably sized chopped wood. (If logs are used they are fed manually in to the
chamber through a hatch door)
The solid biomass fuel would catch fire and burn in a reduced air atmosphere.
A blower would suck the hot gases which are partially combusted down to the gasification area where it encounter hot pyrolytic gas front rising from below.
The partially combusted gases themselves thus are converted to pyrolytic gases and rise up encountering fresh partially burnt gases coming down.
The process thus would be repeated continuously.
The rising hot gas is around 1100 0C and burn off almost all particulate residue in the flue gas thus eliminating all smoke released to the atmosphere.
The heat energy is efficiently transferred to the circulating water at the heat exchanger which is also engulfed in the hot gases during the process.
The 93 0C (or less) hot water in the heat exchanger is then circulated in insulated pipes to the radiators or heating coils installed within the building.
Some Considerations
It is important to maintain a humidity of 20 to 35% in the solid fuel for best results. The hot water in heat exchanger tubes should never be allowed to
exceed a temperature of
93 0C. All good modern gasification boilers have numerous safety devices built in and the hot water thermostat is only one of these.
Your next step
The gasification boiler is an ideal solution for high heating fuel costs that has been neglected for nearly a century due to the callousness of man.
Today when more and more people are realizing the folly of the false euphoria created by fossil fuel vendors for their own benefit these time tested
technologies have resurfaced, of course with much sophistication such as computerized controls, improved material and manufacturing technology.
Gasification boiler option is also a sustainable solution due to which you can derive benefits of many concessions granted
by Sustainable Energy Ireland (SEI) if you opt for one.
