(1) The boiler and all auxiliary equipment are installed, and all tests such as ball passing test, hydrostatic test and air tightness test are qualified.
(2) All rotating devices, feed water pumps, condensate pumps, salt solution pumps, blowers and induced draft fans for coal conveying, combustion and ash removal are qualified for trial operation.
(3) The fuel and water supply are guaranteed, the steam, water and flue gas piping system are normal, and the connection unrelated to the boiler to ...
Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc. Boiler capacity can be expressed by rated evaporation or maximum continuous evaporation. Rated evaporation is the amount of steam continuously produced per unit time under the specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum amount of steam that can be continuously produced per unit time under the specified outlet pressure and temperature.
Manually close the fuel supply valve, stop the combustion, purge after the program enters, until the end of the purge, stop the program such as burning heavy oil, and enter the line sweeping stage before stopping the combustion, and purge with steam or light oil pipe; Generally, steam purging is used when stopping for a long time.
The installation contents of boiler body pipeline are as follows:
1) Connection between water supply console and economizer header;
2) Connection between economizer and inlet pipe from economizer outlet to drum;
3) Connection between the main pipe and branch pipe of the drum drop and each lower header of the water wall;
4) Connection of steam guide pipe between each water wall header and steam drum;
5) Connection of superheated steam pipe between outlet header of low-temperature superheater...
As an important heat energy supply equipment, industrial boiler is widely used in food, electronics, paper making, building materials, textiles and chemical industries. According to the medium, industrial boilers can be divided into steam boilers, hot water boilers and thermal oil heaters. In order to solve the problem "How many tons are the rated thermal power of 42 MW of industrial boiler?" First of all, we need to know the basic knowledge of rated thermal power and unit ton.
According to the power of water or steam circulation, boilers can be divided into natural circulation boilers, forced circulation boilers, once-through boilers and combined circulation boilers.
The steam boiler in the packaging plant is mainly used in the heating process before the raw paper is made into cardboard. In brief, it is using steam which contains no water in the drying process to improve the production efficiency and product quality of packaging cartons. As a result, it has high requirements for the steam and steam boiler, such as temperature, water content, rated evaporation capacity per unit time, etc., which are important parameters in the boiler selection.
