Boiler heat loss

1. The heat loss caused by flue gas emissions from gas boilers is mainly due to the volume of flue gas and the emission temperature. During the exhaust process, if the boiler is not sealed, air flow will carry away some heat, resulting in heat loss. Flue gas emissions account for the largest proportion of heat loss, approximately 4.5%-8.2%.

2. Heat loss due to incomplete fuel combustion, primarily caused by two factors. One is the presence of combustible gas components in the flue gas within the boiler, which is related to the furnace temperature, air coefficient, and the mixing flow of fuel and gas, thereby affecting the volatility rate and content of the fuel. The other is the incomplete combustion of solid fuel, with the more significant factor being that solid fuel is in a granular form. During combustion, if the temperature is not high and the gas flow is poor, the flying ash can easily form sediments. Too much sediment accumulation prevents the remaining fuel particles from being fully combusted, leading to the production of carbon black and causing heat loss in solid fuel gas boilers. Factors such as fuel properties, moisture content, temperature, power load, and the air propulsion force within the boiler can easily lead to fuel heat loss.

3. Heat Loss from Gas Boilers: The heat lost to the external air from the metal structures exposed to the atmosphere, such as the boiler unit, furnace walls, and flues, is referred to as heat loss through radiation. This loss is directly related to the surface area of the boiler unit, its insulation, and thermal insulation conditions.

4. Heat loss from boiler ash sediment: During the combustion process of fuel in a gas boiler, as the internal temperature of the boiler continuously rises, the heat loss that is expelled outside the boiler is referred to as heat loss from boiler ash sediment.

Combustion equipment

During the development of boilers, the type of fuel greatly influences the furnace and combustion equipment. Therefore, it is not only necessary to develop various furnace types to accommodate the combustion characteristics of different fuels but also to enhance combustion efficiency to conserve energy. Moreover, technological improvements to the furnace and combustion equipment require minimizing pollutants (*oxides and nitrogen oxides) in the boiler's exhaust.

Mechanized Grate

Early potshell boilers used fixed grates, primarily burning high-quality coal and wood, with coal adding and slag removal being manually operated. With the introduction of the straight tube boiler, mechanical grates began to be adopted, with chain grates gaining widespread use. Under-grate air supply evolved from non-segmented "uniform warehouse air" to segmented supply. Initially, the firebox was low and inefficient in combustion. Later, the role of firebox volume and structure in combustion was recognized, leading to taller fireboxes and the use of arches and secondary air, thereby improving combustion efficiency.

Room heater

When the generator set power exceeds 6 megawatts, the grate sizes of these layer-fired furnaces are too large and the structures are complex, making them difficult to arrange. Therefore, room-fired furnaces began to be used in the 1920s, which burn coal powder and oil. Coal is ground into coal powder by a coal mill and then injected into the furnace chamber for combustion by a burner, thus the capacity of the generator set is no longer limited by the combustion equipment. Since the early stages of World War II, almost all power station boilers have adopted room-fired furnaces.

Direct Current Burner

Early coal powder furnaces used an "U" shaped flame. The coal powder stream emitted by the burner first descends and then turns to rise within the furnace chamber. Later, a swirl burner arrangement on the front wall emerged, forming an "L" shaped torch within the furnace. As the boiler capacity increased, the number of swirl burners also grew, allowing for placement on both side walls or both front and rear walls. Around 1930, a straight burner arrangement was introduced, positioned at the four corners of the furnace and mostly operating in a circular combustion manner.

Fuel boiler

Post-World War II, with oil prices low, many countries began widely using oil-fired boilers. These boilers were easily automated. After oil prices rose in the 1970s, many countries shifted back to utilizing coal resources. At this time, the capacity of power plant boilers also increased, demanding that combustion equipment not only burn completely and ignite stably, but also operate reliably, have good low-load performance, and reduce pollutants in the exhaust smoke.

In coal-fired (especially lignite-fired) power plant boilers, employing staged combustion or low-temperature combustion techniques, such as delaying the mixing of coal powder with air or introducing flue gas into the air to slow down combustion, or dispersing burners to control furnace temperature, not only inhibits the formation of nitrogen oxides but also reduces slagging. Boiling combustion, a type of low-temperature combustion, can not only combust solid fuels with very high combustible ash content but also can add limestone to the boiling bed for desulfurization.

Gas boiler

Boilers were once a symbol of the industrial age, but with time, these relics of the old industrial era struggle to fully meet the needs of modern enterprises. So, how should boiler companies, beset by diseases, address this issue? Gas boilers can help solve your problems!

Generally, common issues with boilers include being costly and environmentally unfriendly, posing high safety risks, requiring dedicated management due to large space needs, and being麻烦 to operate due to the need for various safety permits. Using a gas hot water heater can address all these issues. Firstly, regarding cost and environmental concerns, gas boilers use combustible gases with zero emissions. They also come with intelligent pressure control, eliminating risks like explosions or carbon monoxide poisoning. Being a high-tech product, these gas boilers occupy less space, are easy to operate without needing a specialist, and run automatically with just a button press. Since they are not coal-fired boilers, no safety permits are required.
