Safe and reliable coal gasification/ coal gas plant/ coal gasifier for sale

HJ coal gas gasifier/coal gasifier is the process of producing coal gas, a type of syngas–a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O)–from coal and water. Coal gas, which is a combustible gas, was traditionally used as a source of energy for municipal lighting and heat before the advent of industrial-scale production of natural gas, while the hydrogen obtained from gasification can be used for various purposes such as making ammonia, powering a hydrogen economy, or upgrading fossil fuels. Alternatively, the coal gas (also known as "town gas") can be converted into transportation fuels such as gasoline and diesel through additional treatment via the Fischer-Tropsch process.

The coal gas gasifiers we manufacture use steam and air as the agent for the mixed coal gas production. The process is that air from blower and self-produced 0.294Mpa steam is mixed to be saturated air as the gasifying agent and comes into gasifier from its bottom via the check value. The block coal is broken up and filtrated to size of 25~50mm or 50~100mm. Then the coal is fed into the coal gasifier by coal feeding system. The gas produced in the stove finally transported to end users after dust removed by gravitational dust cleaner and cyclone dust cleaner.

1. HJ coal gas furnace with 1.5kg standard coal = 12 kw/h electricity =1.1kg diesel

2. Reduce more than 70% cost comparing with electrical furnace, cost 60% lower than oil furnace, reduce 30% cost more than coal stove.

3. Automatic power control system, precise temperature control and high quality heating supply.

4. Continuous automatically deslagging, stable gas producing, convenient operation.

5. Environment friendly and comply with the emission standards of GB9078-96.

Advanced technical design for auxiliary parts on HJ brand coal gas gasifier:
1. Adopting the bucket elevator coal adding system and double bell coal feeding mechanism, the sealing effect is better than before. Combined the adjustable pocket flap and conical coal distributor, the coal can be scattered uniformly, so as to improve coal gasification efficiency, avoiding the un-normal flaming phenomenon.

2. Adopting full water jacket, the steam self-production rate has been improved. No need to provide steam from outside, and the pressure will be stable, it’s better for gasification effect.

3. Adopting tower type pyramid pentagonal grate on the wet rotary ash plate and the material is made by the steels casting, also design a small ash knife to push slag and mechanism to break and press coal slag, it can make the gasification catalyst distributed and the slag falling out uniformly. All the modified structure can make the gasifier has best gas production rate.

4. Adopting isolation of water dust catcher, when the outage of electric and the whole machine, it can improve the sealing effect of the water, so as to cut off the coal gas between gasifier and furnace, guarantying there’ no pressure in the gas pipes and avoiding the tempering explosion.

5. Use the refractory concrete as the roof insulation, it can save cooling water. The coal gas burner is specialized by different models and using conditions, which has features like burning fully, stably operating and service life extended.
