A customer inquired about the operation process of gas boilers. In response to this question, our technical staff provided an explanation.

1. Heating and Drying Phase

Coal, upon entering the furnace and being heated, its moisture begins to vaporize and evaporate. When the gas boiler temperature reaches 100-105℃ on the same day, the moisture has 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 will last.

2. Formation of coke stage from volatiles逸出

As the temperature continues to rise, the 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 sulfur and sometimes a small amount of ash. This portion of carbon and sulfur is also referred to as fixed carbon.

3. Volatile content ignition stage

On the day, when the volatile matter from the gas boiler mixes with the air to reach a certain concentration, the volatiles begin to ignite and burn, releasing a large amount of heat and heating the coke, thus creating conditions for the combustion of the coke.

4. Ash formation stage from coke combustion

As the volatiles approach 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 longer time to burn out, accounting for about 90% of the total combustion time. When the outer layer of the coke burns off and forms ash that obstructs oxygen from diffusing into the center of the coke, combustion stops, resulting in ash and slag.
