Recently, a client reached out to us inquiring about the operation process of gas boilers. In response to this issue, 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 natural gas boiler temperature reaches 100-105°C, 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 from volatile matter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 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
When the volatile components of the gas boiler are released into the air and reach a certain concentration on the same day, they begin to ignite and burn, releasing a large amount of heat and heating the coke, creating conditions for the combustion of the coke.
4. The ash formation stage of 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 burns off first and the resulting ash obstructs oxygen from diffusing into the center of the coke, the combustion will cease, forming slag.
Energy-saving effect of gas boilers is significantly better compared to other types of boilers. In developed countries like Europe and the United States, the proportion of gas boilers is quite high. In our country, due to historical reasons, coal-fired boilers account for an absolute majority. With the severe air pollution in recent years, especially in the Beijing-Tianjin-Hebei region, as well as Shandong, Shanxi, and Henan, winter smog is extremely severe. This has seriously affected people's health. As the public has become increasingly aware and concerned, efforts to protect blue skies are in full swing, with the "Coal-to-Gas" project being a vital sword.Shandong Hezhou PotBoilerAs early as 2003Actively produce high-quality, energy-saving, and environmentally friendly gas boilers.
Shandong He Gu Boiler features the following:
Reasonably designed:
Horizontal internal combustion triple-acting full wet back design100%Wave Furnace Tube,Excellent thermal expansion properties. The water-in-fire overall design, with ample heating surface area and reasonable structural arrangement, ensures the high efficiency operation of the boiler.
High-efficiency energy-saving:
Steam and hot water boiler series feature high thermal efficiency of97%-99%The large combustion chamber, combined with a rational structural arrangement, can transfer more heat into the water, significantly enhancing the heat-exchange efficiency between fuel and steam, as well as fuel and hot water.
Meets environmental standards:
The combustion chamber is spacious, maximizing radiant heat exchange, and coupled with high-quality and reliable imported burners, the fuel is fully combusted, significantly reducing harmful emissions in the flue gas. Our company's fuel (gas) steam and hot water boilers have passed official departmental testing, meeting national environmental protection standards and are ideal eco-friendly products.
Superior configuration:
World-renowned burner compatibility, advanced control systems (with imported main components), valves, and pumps all utilize top-quality national products. An excellent boiler accessory configuration ensures robust security and stable operation for the boiler.
Fully Automatic Operation:
With just a push of the start button, the boiler operates according to the pre-set program, with load regulation and water supply all running automatically—no need for constant supervision.
Ease of maintenance and repair:
Boilers are equipped with movable smoke box doors at both front and back, featuring observation holes and inspection ports at the rear for easy access into the furnace for inspection and cleaning. Manholes are also provided on the boiler body, with a structural design that ensures convenient maintenance and future repairs.
