In the combustion process of solid fuel, some fuel often leaves the boiler with ash or fly ash without burning. This part of heat loss is called the heat loss of incomplete combustion of solid, which means q4 in boiler.
According to the inverse balance calculation formula of boiler thermal efficiency, the thermal efficiency of the boiler is equal to the calorific value minus various heat losses. For the boiler with solid fuel, the heat loss of solid incomplete combustion is the main heat loss i...
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 biomass fuel and inferior coal. During use, all parts of the boiler are playing their respective roles.

The working process of circulating fluidized bed boiler is to send air into the fu...
Coal-fired boilers use various types of coal as fuel. After the heat of coal is converted, steam is generated, which is often used in the production of heating, heating and thermal power generation. The model parameters of coal-fired boilers are different, and the cost is also different. Here, ZOZEN Boiler takes the cost of a 40-ton steam coal-fired boiler as an example for a brief introduction.
40 tons of steam coal-fired boiler cost
In addition to boiler room construction, EIA costs, transpo...
Gas boilers use clean energy as fuel, produce less pollution and have high thermal efficiency, and are widely used in all walks of life to help major enterprises achieve green development. However, there are many types of boilers on the market with complex performance parameters, and it is difficult to purchase a cost-effective gas boiler. Taking the price of 2 tons of natural gas steam boiler consulted by some users as an example, ZOZEN Boiler explains how to judge the cost performance.2-ton na...
Thermal oil heater, also known as organic heat carrier boiler, is a kind of special equipment. In order to control the safety of the boiler, relevant departments have certain specification requirements for the material of heat-conduction oil boiler. In this paper, as a professional heat-transfer oil boiler manufacturer, ZOZEN Boiler will show you what kind of material is used on the boiler body of the thermal oil heater.

As for the material of heat...
Circulating fluidized bed boiler is a kind of equipment with high efficiency and low pollution, and it has been widely used in power station, industry and other fields. Circulating ash is an important part of circulating fluidized bed boiler, which changes with the running state. So what are the functions of circulating ash of circulating fluidized bed boiler?
The role of circulating fluidized bed boiler circulating ash
The circulating ash in the circulating fluidized bed boiler consis...
The exhaust gas loss of thermal oil heater refers to the heat that is taken away with the exhaust of flue gas, which is called exhaust heat loss. The heat loss of boiler exhaust flue gas is particularly important, accounting for a large proportion, about 4~8%. So what causes the high exhausted gas temperature of the thermal oil heater?
Boiler exhaust gas temperature standard
Before explaining what causes the high exhaust gas temperature of the thermal oil heater, let you first understa...
Boiler heating is not a single boiler equipment, but heating through the boiler thermal system. So what is the boiler thermal system and what does it include?
What is the boiler thermal system
Boiler thermal system refers to the general term for conveying equipment, heat pipes, control valves, measuring instruments and monitoring instruments for conveying and distributing heating medium in the boiler room.
The role of the boiler thermal system:
1. It plays the role of connecting the ...
