Evaporation tube bundle and water cooling tube panel are two important heating surfaces of the boiler, which are all arranged inside the boiler, so it is not easy to see them intuitively.
Boiler evaporation tube bundle
Evaporation tube bundle mainly absorbs convection heat transfer in small and medium-sized boilers. Generally, it is a bundle of dense staggered piping systems consisting of ascending pipes and descending pipes that connect the upper and lower drums. The heat load of the ...
Thermal oil heater is a boiler that uses heat conduction oil as heat medium to transfer heat. What is the meaning of low nitrogen thermal oil heater in Shanxi? We can understand it by disassembling the key words into Shanxi, low nitrogen and thermal oil heater. Shanxi refers to the region of Shanxi Province; Low nitrogen refers to the low emission of nitrogen oxides from the boiler, generally referring to 30mg/Nm³ and 50mg/ Nm³; Thermal oil heater is a common type of boiler. Therefore,...
100-ton gas-fired hot water boiler refers to the gas-fired hot water boiler with rated heat supply of 70MW. 100-ton gas-fired hot water boiler is often used for central heating in cities or park heating.
The furnace body structure of ZOZEN SZS series 100-ton gas-fired hot water boiler adopts large-volume furnace design, and with the imported ultra-low nitrogen burner, it can effectively inhibit the generation of NOX, which is better than the emission standard of 30mg/Nm³. With wast...
Circulating fluidized bed boiler (CFB) is a fluidized combustion boiler. Its main structure includes combustion chamber and circulating furnace. It has many advantages such as high thermal efficiency and low pollution, and is especially suitable for inferior coal. During use, all parts of the boiler are playing their respective roles. Here, we will focus on the function of the separator of circulating fluidized bed boiler.
The working principle of circulating fluidized bed boiler separa...
Low-carbon condensing gas boiler takes clean energy natural gas as fuel, and uses high-efficiency flue gas condensation waste heat recovery device to absorb sensible heat and latent heat released by steam condensation in the tail of the boiler, so as to achieve the purpose of improving boiler thermal efficiency and saving energy, thereby reducing carbon emissions.
Low-carbon gas-fired boiler recovers the energy from the hot flue gas (generally around 140℃) emitted by the boiler through ...
How to change the coal boiler to natural gas boiler?
I. Boiler selection
How to change coal to natural gas involves many aspects, such as boiler body, gas supply system, air system, burner system, ignition system and smoke exhaust system.
1. Under the condition that the total heat demand is constant, the total tonnage of the boiler after changing to natural gas can be constant; If the total heat consumption increases or decreases, it needs to be adjusted in time to ensure the heat consumption...
In China, industrial boiler is a kind of important thermal energy supply equipment in the national economy. Electric power, machinery, metallurgy, chemical industry, textile, paper making, food and other industries, as well as industrial and civil heating, all need boilers to supply a large amount of heat energy. Boiler uses the heat energy or other energy released by fuel combustion to heat the working medium (intermediate heat carrier) to a certain parameter. Due to the particularity of indust...
Advantages:Chain grate is a kind of better combustion equipment in layer combustion furnace. Compared with gas-fired boilers on the market, the solid fuel used in chain grate boiler does not need pipeline laying, and the cost is relatively low. Moreover, the chain grate boiler system is simple, and the manufacturing cost and operating cost are relatively low.
Disadvantages:The chain grate boiler has a limit on the coal types. The combustion mode of the chain grate is moving hearth combusti...
