In its early stage, Gasification Furnace was fixed-bed type, by utilizing the incomplete combustion of biomass fuel in the furnace to produce biomass gas due to lacking of oxygen. In recent years, the application of fluid-bed combustion technology makes the Gasification Furnace have still higher energy conversion efficiency together with simple, stable and reliable operation of the furnace. Besides, the thermal value of biomass gas has greatly been raised, reaching up to 5.0-6.3MJ/Nm3 (1,200-1,500kcal/Nm3).

The discarded biomass fuel shall be pyrolysised and gasified at high temperature in the furnace and change into biomass gas which can be used after cleaning and cooling treatment as clean gas fuel of internal combustion engine for electric power generation or for supplying urban residents as gas used as household fuel, or for supplying gas to the boilers of rice mills and timber processing mills as hot air furnace -combustion to produce steam or hot-air. The gasification furnace manufactured by using the patent technology has been equipped with a tar cracking apparatus, which is capable of making the gas-phase tar in the biomass gas split to the gas fuel with lower molecular weight. While by providing specially designed dust-removing and tar-removing equipment outside the furnace, by adopting multi-methods have been adopted to strictly purify the biomass gas. This furnace is also equipped with perfect operation parameter monitoring instruments of operational, together with centralized control and remote operation to meet the requirements of the internal combustion engine for fuel quality. The gas output of the furnace has been already serialized and can meet the demand of gas supply for 200-2,000kW electric power generation. The specifications and parameters are shown in the Attached Table 1.2. If customers have special requirements, unique design, manufacture and delivery can be made on your demand. For the customers who need pretreatment of biomass fuel crushing and drying, we can provide corresponding complete sets of equipment and we also can select and match auxiliary machines and affiliated apparatus for gasifying and purifying system equipment depending on specific situation, such as water treatment in order to ensure the safe and economical operation.
