Introduction to the two-stage gas generator
The two-stage gas generator has upper and lower gas outlets that can output gas with different calorific values. Its gasification efficiency and comprehensive thermal efficiency are both higher than that of a single-stage furnace. Coal passes through the furnace The inner upper section is thoroughly retorted, the lower section gas basically contains no tar, and the upper section gas contains a small amount of light tar, which is not easy to block the pipeline. The two-stage furnace gas has high calorific value and stable operation, high flexibility, high degree of automation, and low labor intensity. The two-stage furnace gas station does not pollute the environment, saves water, has a small footprint, and has low long-term operating costs. The grate rotation and coal adding parts of this furnace type can be mechanical or hydraulic according to different user requirements. The grate is made of heat-resistant cast iron, which has better air permeability and is suitable for the bituminous coal gasification process.
Two-stage gasifier process
The qualified raw coal is lifted by an electric hoist to the coal storage bunker of the main factory building and then added to the furnace through a double-drum hydraulic stoker. The coal is heated and carbonized by the gas from the gasification section. The coal in the semi-coke state reacts with the gasifying agent (air vapor) in the gasification section. The gas generated in the gasification section is divided into two parts. One part is discharged from the gas outlet of the lower section of the two-stage gas generator through the cyclone dust collector, and the other part passes upward. The central tube and the retort gas are mixed and come out from the gas outlet of the upper section. The gas at the outlet of the lower section is cooled and dusted by the cyclone dust collector, then enters the forced air cooler to continue dust removal and cooling, and then enters the intercooler for further cooling. The gas at the outlet of the upper section enters the electric tar collector to remove coke and then directly enters the intercooler to mix with the gas in the lower section. After the mixing is completed, the temperature is lowered and mixed. After mixing, the gas enters the electric light oil collector to capture light oil. The gas is pressurized by a pressurized fan and sent to the water mist. The drip catcher dehydrates and sends it to the user.
