What are the ways to increase gas production in a φ2600 gas generator?

There are two main approaches (in principle): one is to improve the thermal efficiency of the entire furnace, and the other is to use oxygen-enriched or pure oxygen for gas production

1. Ensure high-quality raw materials. 2. Optimize manufacturing processes. 3. Maintain equipment to prevent leaks. 4. Strengthen management and performance evaluation

1. Ensure the quality of the raw materials: the coal fed into the furnace should be as uniform and clean as possible, with as little surface debris as possible. 2. Optimize the manufacturing process and strengthen management so that operators can increase production. 3. Eliminate leaks.

Generally, there are the following points: (1) Increase the exhaust intensity. Increasing the blowing intensity not only boosts the reaction rate, shortens the blowing time, and increases the effective gas production time, but it also suppresses side reactions and reduces consumption. Specifically, fans with higher wind pressure are used, the air inlets and valves for the furnace are enlarged to Dg600, furnace grills with a large ventilation area and low gas resistance are selected, and the blowing time is adjusted according to temperature and relative humidity. (2) The upper and lower temperatures are properly controlled to increase the amount of gasification. (3) Reduce system resistance and control the steam pressure entering the furnace appropriately. (4) Appropriately increase the carbon layer height. The height of the carbon layer is primarily determined by the blowing intensity; appropriately increasing the height of the carbon layer can boost the rate of water vapor decomposition and increase the gas production volume. (5) Strictly control the quality of coal fed into the furnace. (6) Adopt effective new technologies and equipment, such as: air blowing recovery systems ； Micro oil pressure automatic control system ； Steam feed to the furnace from the self-regulating hydrogen-nitrogen ratio control system ； Temperature, flow rate, and gas composition detection system.

1 Ensure the quality of raw coal fed into the furnace. 2 Optimize process parameters. 3 Adopt new processes: such as installing air blowing recovery devices to improve waste heat efficiency

Burn the coal properly； Tapered jacket, modified into a Φ2800 tapered furnace ； By improving the ventilation of the furnace grates, the blowing strength increases, which in turn leads to a higher gas production volume.

1. Small-scale furnaces have high requirements for coal; bituminous coal is generally used, with a particle size of 8–35 mm being appropriate. 2. The steam temperature and pressure should be stable; low-pressure steam is usually used. 3. Pay attention to optimizing the blowing time and the amount of steam added. Everything has been covered in detail above; these are just a few additional points

There are too many factors to consider: high-efficiency fans that increase the strength and efficiency of air blowing; appropriate grates that ensure even distribution of vaporization; good explosion-breaking capabilities; guarantees for steam quality; prevention of water in the steam; proper pressure levels that prevent the furnace temperature from becoming too high while also reducing heat consumption; ensuring an adequate rate of steam decomposition; adjusting the quality of coal fed into the furnace; and appropriate system pressure. It’s not about simply lowering the system pressure – it needs to be set at the right level. Process optimization is necessary, as well as frequent communication with the operators on the job, as they have the most experience: lol

Currently, raw material prices are on the rise, which naturally increases costs; our company uses small-grained white coal. As long as the height of the carbon layer, the temperature at the gas outlet, the amount of steam, and the amount of primary air are properly controlled, and the equipment is cleaned thoroughly on a regular basis, there will be no problems with gas production.

The load of the furnace refers to the volume of primary air (air supplied to the furnace). The greater the amount of air supplied to the furnace, the more complete and intense the combustion during the blowing phase, and the more heat is generated; consequently, the gas production per furnace also increases. Based on experience, to increase the gas production per furnace, it is necessary to raise the carbon layer thickness and increase the amount of air fed into the furnace; at the same time, a certain amount of oxygen must be added (depending on the available conditions in each enterprise). Increasing the oxygen content in the air fed into the furnace allows for faster operation of the furnace, enabling short combustion periods with strong airflow, which in turn increases the proportion of useful gases in the final gas product – this is also very important................
