Boiler heat loss

1. Heat loss caused by flue gas emissions from gas boilers is primarily due to the volume of flue gas and the temperature of flue gas emissions. During the exhaust process, when the boiler is not in a sealed state, air flow carries 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 volatilization speed and content of the fuel. The other is the incomplete combustion of solid fuel, more influenced by the granular nature of the solid fuel. During combustion, if the temperature is not high and the airflow is poor, the flying ash can easily form deposits. Too many deposits accumulated prevent the remaining fuel particles from being completely combusted, leading to the formation 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 Dissipation of Gas Boilers: The heat lost to the external air through the metal structures exposed to the atmosphere, such as the boiler unit, furnace walls, and flues, is referred to as heat dissipation. This loss is directly related to the surface area of the boiler unit, as well as the insulation and thermal insulation conditions.

4. Heat loss from boiler slag sediment: During the combustion process of fuel in a gas-fired boiler, as the internal temperature of the boiler continues to rise, the heat loss caused by expelling the heat outside the boiler is referred to as boiler slag sediment heat loss.

Combustion Equipment

During the development of boilers, the type of fuel greatly affects 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, technical improvements to the furnace and combustion equipment require minimizing pollutants (*oxides and nitrogen oxides) in the boiler's exhaust smoke.

Mechanized Grate

Early pot shell boilers used fixed grate, mainly burning high-quality coal and wood, with manual operation for coal addition and slag removal. With the advent of straight tube boilers, mechanical grates were introduced, and chain grates were widely employed. Air supply beneath the grate evolved from non-segmented "total storage wind" to segmented air supply. Initially, the furnace was low and had low combustion efficiency. Later, the role of furnace volume and structure in combustion was recognized, leading to taller furnaces, the use of arches and secondary air, thereby enhancing combustion efficiency.

Room combustion furnace

When the generator set power exceeds 6 megawatts, the grate sizes of these layer combustion boilers are too large, the structures are complex, and they are not easy to arrange. Therefore, room combustion boilers began to be used in the 1920s, burning 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 been using room combustion boilers.

DC Burner

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

Fuel boiler

Post-World War II, with oil prices low, many countries began widely using oil-fired boilers. The automation level of oil-fired boilers is easy to enhance. After oil prices increased in the 1970s, many countries reverted to utilizing coal resources. At this time, the capacity of power plant boilers also grew larger, 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, the use of staged combustion or low-temperature combustion technology, such as delaying the mixing of coal powder with air or adding flue gas to 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, which is a type of low-temperature combustion, can not only burn solid fuels with very high combustible ash content but also can incorporate limestone into the boiling bed for desulfurization.

Gas Boiler

Boilers once symbolized the industrial era, but as time has passed, this product of the old industrial age is hard to fully meet the demands of modern enterprises. So, how should a boiler company burdened with diseases find a solution? Natural gas boilers can help you out!

Generally, common issues with boilers include being costly and environmentally unfriendly, posing high safety risks, requiring dedicated management due to their large space needs, and being麻烦 to use due to the need for various safety permits. Using a gas hot water heater can address all these issues. Firstly, it solves the problem of being costly and environmentally unfriendly, as gas boilers use combustible gases with no emissions. They also come with intelligent pressure control, eliminating concerns about explosions or carbon monoxide poisoning. Being a high-tech product, gas boilers are space-saving, easy to operate, and do not require a dedicated operator; just press a button and they run automatically. Since they are not coal-fired boilers, no safety permits are needed.
