Coal-fired boiler economizer, as its name implies, is a boiler device to save energy. The structure of coal-fired boiler economizer is relatively simple, which is mainly composed of all stainless steel 304 frame and stainless steel spiral finned tubes, all of which are arranged in a certain order.
According to the power, size and price of the boiler, the boiler economizer adopts different materials such as stainless steel and ND steel. According to the medium, coal-fired boiler economizer is ma...
The main water quality indexes of medium and high pressure steam boiler water are hardness, dissolved oxygen, iron, copper, sodium and silicon dioxide.
Boiler steam pressure control refers to maintaining the steam pressure of boiler drum by adjusting the fuel control system. Its basic task is to adapt the heat provided by fuel combustion to the steam load of boiler drum. At the same time, it is necessary to ensure the safe and economic operation of boiler drum and meet the requirements of environmental protection.
To buy dust removers for coal-fired boiler with good cost performance, we should first know more about the manufacturer, quotation and market. After all, a good vendor can bring more help to customers. Therefore, determining the sales manufacturer will be the focus of purchasing coal-fired boiler dust collectors. Coal-fired dust remover has high efficiency and will have more outstanding performance in use. Of course, when selecting products, we should know the quality of coal-fired boiler dust removers, so as to choose equipment with reasonable price and stable performance.
The price difference of coal-fired boiler dust remover is mainly due to the different specifications and models.
Mechanical dust remover is a device that separates dust particles from airflow by using mass forces (such as gravity, inertial force and centrifugal force). Such as gravity dust remover, inertial dust remover and cyclone dust remover. Mechanical dust remover is characterized by simple structure, low cost and convenient maintenance, but its dust removal efficiency is low.
Removal of metallic scale and corrosion products generally requires chemical cleaning. Acid or chelant cleaning procedures vary greatly depending on individual circumstances. Chemical cleaning can improve the boiler heat rate and reduce the number of tube failures. It typically improves the stability of boiler chemistry.
To guarantee the successful and efficient shell boiler operation, the user must:
1)Know the conditions, environment, and demand characteristics of the plant, and accurately specify these conditions to the boiler manufacturer.
2)Provide a boiler house layout and installation that promotes good operation and maintenance.
3)Select the control systems that allow the boiler to operate safely and efficiently.
4)Select the control systems that will support the boiler in supplying dry steam to the plant at the required pressure(s) and flowrate(s).
5)Identify the fuel to be used and, if necessary, where and how the fuel reserve is to be safely stored.
In the operation of gas-fired steam/hot water boiler, it need continuous water supply to ensure the water volume in the drum. Once water shortage occurs, it will cause the boiler dry burning problem, which will further result in the boiler failure and other problems.
