If the coal feeding air flow rate to the coal feeder of a fluidized bed boiler is too high or too low, it can have several effects on the operation of the boiler:
1. Too high coal feeding air flow rate: if the air flow rate to the coal feeder is too high, it can cause the coal to be blown out of the feeder and into the furnace too quickly, which can result in incomplete combustion and high emissions of unburned hydrocarbons and carbon monoxide. This can also cause fluctuations in the be...
Circulating fluidized bed boiler is a type of boiler that uses circulating fluidized bed technology to burn solid fuels. It has several advantages:
1. High efficiency and energy-saving: circulating fluidized bed boiler uses circulating bed technology, where the particle material in the bed forms a circulating flow, effectively improving the heat transfer efficiency. As a result, the thermal efficiency of the boiler can reach more than 85%, and the energy-saving effect is significant.
2. Good c...
Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations.
How Do Boiler Economizers Work?
A boiler economizer is essentially a heat exchanger that recovers w...
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...
Different combustion modes are the core difference between fluidized bed boiler and common boiler.
Fluidized bed boiler adopts fluidized combustion mode. After the fuel is crushed to a proper particle size by a crusher, it is fed from the upper part of the air distribution plate of the combustion chamber by a coal feeder, mixed with the hot boiling materials in the combustion chamber, heated rapidly, and the fuel quickly catches fire and burns. Under the action of high air velocity, a large num...
As an effective tool in the era of environmental protection, gas-fired boilers are favored by all walks of life and widely used in food, paper, building materials, wine, chemical industry and other industries. With the increasing use of gas-fired boilers, there are more and more problems.
The key difference between vapor and steam is that vapor is a generally used term while steam is the technical and specific term. A shared attribute between vapor and steam is the point of origin or how it is formed. Steam and other kinds of vapor are often made by evaporation or with other means or application of heat.
Steam is very widely applied in the textile industry. It is commonly used in many subsectors and processes: manufacturing fabrics, manufacturing textile products…
