Working principle:
Qualified raw coal is lifted by electric hoist to the coal storage bunker in the main plant, and then added into the furnace through double-drum hydraulic stoker. The coal is heated and distilled by the gas from the gasification section. The semi-coke coal after distillation reacts with the gasifying agent (air, steam) 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-section furnace through the cyclone dust collector, and the other part goes up through the central pipe to mix with the distillation gas and is discharged from the upper gas outlet.
The coal gas at the outlet of the lower section enters the forced air cooler after being cooled and dusted by the cyclone dust collector, where it continues to be dusted and cooled, and then enters the intercooler for further cooling. The coal gas at the outlet of the upper section enters the electric tar precipitator for decoking, and then directly enters the intercooler to mix with the coal gas at the lower section, where it is cooled during mixing. After mixing, the coal gas enters the electric light oil catcher to remove light oil, the gas is pressurized by a booster fan and sent to the gas desulfurization tower to remove hydrogen sulfide. After multi-stage dust removal, coke removal, and desulfurization, the coal gas is sent to the gas consumption point through pipelines.

Advantage:
1. The calorific value of coal gas is higher than single stage gas producer.
2. The thermal efficiency is 10% higher than single stage gas producer.
3. Low-temperature dry distillation coal tar has low viscosity and good fluidity, and can be used as high-quality fuel or further refined and processed.
4. The cooling of coal gas can be done by indirect cooling. The circulating water quality of coal gas cooling is clean, the amount of condensed water of the phenol-containing dry distillation coal gas is small, and it is easy to handle to meet the standards, which is beneficial to the improvement of environmental protection.
5. After the coal gas is detarred, it can be transported to 300-400 meters away without heating.
6. The coal gas is cooled and detarred to remove impurities, and can be transported over long distances if pressurized.
7. Through desulfurization, cold and clean desulfurized gas can be produced, which can be used in industries with high requirements on coal gas cleanliness, such as gas power generation, firing of ceramic sanitary ware, etc., and can meet the requirements of most industries.
8. Wide applicability of coal: lean coal, non-sticky bituminous coal, long bituminous coal, bituminous coal with an expansion index less than 2.5, and some lignite can be used.

 

Application:
The gas produced by the two-stage gas producer cold gas station can be widely used in industrial heat treatment, suitable for the steel industry, forging, ceramic firing, gas power generation, ore drying, and various heat treatment furnaces.

FAQ

Q: How can we determine the specific model we need?

A: Configure the appropriate device model for the customer according to their needs.

 

Q:  Are your real manufacturer?

A: Yes,we have our own big factory ,anytime welcome your visiting .

 

Q: Do you provide technical support?

A: We assign engineering and technical personnel to the user’s site to guide them in planning the site and designing the installation process.

 

Q: Is there any quality inspection on the products?

A: The products will be strictly inspected before leaving the factory, and video inspection can be provided.

 

Q: What is the difference between a cold gas station and a hot gas station?

A: The difference between hot and cold gas lies in the difference in sensible heat of the gas. The combustible components of the gas remain unchanged, so the calorific value does not change much.
