3.0 two stage coal gasifier (cold coal gas)
Introduction

At present, our country mixed coal gasifier mainly separate single stage and two stage two types, while two stage gasifier, its gasification and overall efficiency are better than single stage, operating is high flexibility, low labor strength, good adaptability, (suitable for bitumite coal), especially due to coal gasifier station all adopt closed-circuit circulation, without environmental pollution, significant in water-saving, long-term operation cost is low, so it was widely used due to these characteristics.

Our company is the professional manufacturer of coal gasifier, for many years of production and practice, we cultivate and own a professional technical team in design, manufacture, installation and after sales service. Company take “Pursuit of quality” as principle, “Credibility must comes first” for the tenet, with short lead time, low price and best service, has won extensive customers trust. Our company developed the new two stage gasifier, mainly suitable for smelting, ceramics, chemical industry, machinery industry, etc. Integrating the advantages of other manufacturer, combining user’s actual using station, made many applicable and beneficial process improvements, making the two stage gasifier structure more reasonable, more convenient for using, construction cost is low, more shorten the construction period.

3.0 two stage coal gasifier (cold coal gas)
specific features as below:

1. two stage Coal gasifier ontology structure changed into pressure vessel compression equipment. Inside gas station system has removed outer matched steam boiler, increased waste heat boiler, utilizing gas waste heat make itself produce 0.3Mpa steam, fully can meet gas station itself steam usage amount, no need additionally built boiler or use outside steam, reduce the gas station running costs.

2. two stage Coal gasifier ontology full weight changed undertaken by underground foundation, coal gasifier plant only as worker’s operating room. Thus make gasifier plant structure becomes simple, project cost sharply reduced. According to user’s opinion the plant can use simple steel structure, which is not only reduce the project cost, also shorten the construction period.

3. The lower stage gasifier using simple cyclone dust separator, which is simple and practical, saving the investment.

4. two stage Inside gas pipes, especially upside gas forepart and low side gas forepart all using water sealed valve instead of mechanical valve, in this already played a role of cutting, also can be used as gas safety relief-pressure device, make coal gas pipe system’s cutting safe and reliable.

Two stage Coal gasifier working principle:

Two stage Coal gasifier is making coal transform into combustible gas—coal gas (its main ingredients is C0, H2, CH4, etc.) production equipment. Two stage gasifier main work principle: after screening of complied coal gasification, through stoker add into coal gasifier, coal inside gasifier through physical and chemical reaction produce combustible gas, through upper, lower exit into cooling, purification, mixing equipment then transported into kiln for heating.
