Recently, a client inquired about the operation process of a gas boiler. In response to this question, our technical staff provided an explanation.
1. Heating and Drying Stage
After coal enters the furnace and is heated, the moisture in the coal begins to vaporize and evaporate. When the gas boiler temperature reaches 100-105°C on the same day, the moisture is completely evaporated, and the coal is fully dried. The duration of the heating stage varies depending on the amount of moisture in the coal; the more moisture, the longer the drying stage.
2.逸出挥发性分，形成焦炭阶段
As the temperature continues to rise, dry coal begins to decompose, releasing combustible gases known as volatiles. After the volatiles are released from the natural gas boiler, the remaining solid material is called coke, which is almost entirely carbon, with some ash and occasionally a small amount of sulfur. This portion of carbon and sulfur is sometimes referred to as fixed carbon.
3. Volatile fraction ignition stage
On the day, when the volatile components of the gas boiler mix with the air to reach a certain concentration, the volatiles ignite and burn, releasing a large amount of heat and heating the coke, creating conditions for the combustion of the coke.
4. Ash and slag formation stage from coke combustion
As the volatile matter approaches complete combustion, coke begins to burn, which is a chemical reaction between solid fuel and oxygen in the air. The combustion of coke is slow and takes a long time to burn out, accounting for about 90% of the total combustion time. When the outer shell of the coke has been burned off and the resulting ash obstructs oxygen from diffusing into the center of the coke, combustion will cease, forming slag.
