For example: maximum biomass consumption per hour is 0.3 – 0.5 tons, how many Kwh will this produce and how much heat?
1kg wood chips can produce 2-3m3 syngas , 2.5m3 syngas can generate 1kw electricity. It means 0.3-0.5ton wood chips can produce around 300-500kw electricity, the whole system can get around 1000000kcal heat, can be used for room heating.
What happens when the plant runs at a smaller capacity, or at a larger capacity?
When gas supply is insufficient, Gen sets will stop working, when gas supply is sufficient, because self-priming function of Gen sets, we can make a corresponding adjustment,to achieve continuous and stable operation .
What about the emission from the power plant, do you have a test data?
es, we installed a 500KW MSW power plant in Thailand and we have experience data: Emission Thailand’ standard 500KW emission SO2 30PPM 10-20PPM NO2 250PPM 200-230PPM HCL 136PPM 80-120PPM DIOXIN 30ng/NM3 5-10ng/NM3 Total supended particle 40mg/NM3 20-30mg/NM3
Can we use the waste heat from gasification system for house heating or hot water boiler? If yes, how many of the waste heat can be from 500KW power plant?
The heat waste is about 2000000Kcal/h from 500KW power plant, and we can use it for house heating or circulation with hot water boiler.

60m*3m, not included sewage pool and water circulation pool. The sewage pool need to check the moisture of raw material, the water circulation pool need to check your local climate. Normally, we need to do maintenance each month and a full inspection once every three months. The power plant can work 300days, so we can get 3,600,000KWH each year.
How many of your power plants are in operation and where are they located on oversea market?
100KW wood chips gasification power plant in Congo, April 2014 200KW wood pellet gasification power plant in Russia, April 2014 500KW city waste gasification power plant in Thailand, March 2015
Can we use the syngas for electricity?
The combustible gases from the gasifier can be used a) in internal combustion engines, b) for direct heat applications and c) as feedstock for production of chemicals like methanol. In order for the gas to be used for genset, it should be cleaned of tar and dust and be cooled.
Can we use only plastic waste as fuel for gasification?
If it is difficult to find more biomass material, it is ok to use plastic waste as fuel for gasification, but the gasifier will need extra biomass material at the beginning, then put plastic waste inside gasifier furnace for gasification. To discharge ash automatically, we need to put extra biomass material before gasifier stop working.
Can we get more detail, 1ton/h wood chips gasifier, what is the output of gas, wood tar, what utilities are required, operational cost, electricity?
The output of gas is about 2500M3/h The wood tar is about 150-200KG/h The ash is about 100kg carton. Two workers will be needed for the operation. The electricity is 40.5KW each hour Water and tar(heavy oil) are together, so we can make about 5m*6m*3m pool to handle sewage, and get heavy oil from it. The chemical material will be needed to make water meet the requirement of environment requirement.
What we can get from gasifier, only syngas?
If the raw material is 1ton wood chips, we can get about 2500m3 syngas, 100kg carbon, 150-200kg wood tar.
What is the content of the syngas from gasifier, and the heat value?
1300-1500Kcal per cubic meter, and the content of the syngas depends on the raw material. Normally, the components of bio syngas from wood chips: CO 20-25%; H2 10-13%; CH4 2-4%; CmHn 0.8% H2S 16.4mg/Nm3; CO2 13%; O2 1%; N2 46% Industry & city waste gas components: CH4 9.77%; C2H6 1.75%; C2H4 4.68%; C3H8 0.33%; C3H6 2.33%; C4H10 0.07% C4H8 0.76%; C5H12 0.02%; C5H10 0.26%; H2 12.95%; CO2 36.39%; CO 30.69%
What is the requirement of fuel for gasifier, can we gasifier coal or sewage sludge?
Moisture≦15%, size≦10cm But coal or sewage sludge can be gasification. We can use coal powder 150-20mesh as fuel for wood powder burner, and sewage sludge is also possible as fuel for our burner.
Which material is suitable for biomass gasifier, can we also use city waste as fuel?
Yes, it is ok to use city waste as fuel, and the raw material includes PP (Woven bag, microwave tableware, POTS, ),PE (Bottle, bucket, kettle, plastic food bag) , PC(Plastic cups, cutlery, sports equipment), PS(Disposable plastic tableware, comb, box, ball-point pen rod, children's toys, plastic shopping bags),PET (Medicine bottle, cosmetics bottle, cap and plastic bottles), HPDE(All kinds of recycled plastic), Rice husk, woodchips, sawdust, bark, shavings, crop stalks, coconut hull, olive pomace, bagasse, plastic waste, palm shell, cotton straw.......
What is the meaning of biomass gasification, is it a new technology?
Biomass gasification means incomplete combustion of biomass resulting in production of combustible gases, including Carbon monoxide (CO), Hydrogen (H2), Methane (CH4), CmHn, this mixture is called pyrolysis gas that can be used to run internal combustion engines, and generate CHP. Gasification is a century old technology, which flourished quite well before and during the second world war. Today, because of increased fuel prices and environmental concern, there is renewed interest in this century old technlogy. Gasification has become more modern and quite sophisticated technology.
Can you make a brief introduction to compare your three type biomass burner?
Biomass pellet burner has the best price, owing to it has a hopper together with body. The pellet is easy for delivery and store. Biomass sawdust burner has an extra fuel bin, so the price is higher than pellet burner, but the sawdust has the lowest cost compared to pellet and wood powder. The efficiency is 90-95%. Biomass wood powder burner also need an extra fuel bin, but it has the best performance 95-98%.
How many people operate this biomass burner and what about the lifetime of your equipment?
The operation is simple and a single person on duty can finish the work. The buyer should operate the biomass burner according to the operation manual the seller supplied and 8-10 year is no problem.
If we need your engineer to guide installation and operation for biomass burner, how long will be finished? What about the temperature of the frame?
Normally, 2-3 working days will be ok if all equipment are ready. The frame is about 900-1100degree.
What about the emission of biomass burner, does it pollute environment like coal boiler?
Ash<1~1.5%, flue gas emission<50mg/m3 Biomass burner use wood pellet, sawdust, wood powder or other agriculture waste, which are recyclable and environmental-friendly, not like the coal producing large amounts of waste and dust.
What about the ignition device, can I ignite biomass burner without this device?
It is diesel automatic ignitor for 5-8minutes, Brand BALTUR from Italy It is ok to ignite burner without this device, and we can use burning material instead of ignitor.
What is the advantage of your water cooling system compared to air cooling for biomass burner?
If biomass burner connect with boiler, it is ok to use the cold water from water and the hot water back to boiler, in this way, it can save energy compared to fan cooling. The water pump is smaller than air fan and it can save electricity consumption. The cooling time will be more fast than you use the fan.
What is working principle of the biomass burner?
The combustion furnace adopts 3-layer thermal insulation, the inner furnace adopts high aluminum refractory ,anti-souring and high temperature resistance. Outside of the furnace, it uses water cooling system Multiple air increasing, high temperature pyrolysis, semi-gasification suspension combustion, heat convection and radiation together, combustion last for more than 2 seconds, high-speed combustion and no dead corner.
What is the usage of the biomass burner, only for boiler?
It is widely used to connect with Fuel gas/oil/coal boiler industry (steam boiler, thermal oil furnace, hot water boiler), smelting industry (aluminum melting furnace, reverberatory furnace), drying industry (food drying, sawdust/wood chips/biomass drying), spray coating industry (metal spraying, electroplating heating), greenhouse, building industry (asphalt heating).
This biomass burner can work continuous or not?
Yes, 24hour/days is no problem.When we discharge ash, it is no need to turn off the burner, owing to the system is micro negative pressure operation, ensure no gas or fire leakage.
What is requirement for the raw material?
Moisture should be less than 15% Size: 6-8mm for pellet burner, 10*20mm for wood chips burner, 1-3mm for sawdust burner, 60-80mesh for wood powder burner. It will be better to use good raw material and remove impurity as much as we can.
