What Are the Different Boilermaker Jobs?
Boiler is a special equipment for heating and industrial use. In terms of domestic heating, there are mainly two types of hot water and steam, such as domestic hot water and bath water. Industry mainly provides steam to provide refrigeration, power and other services for other equipment, such as ships, locomotives, mines and other places. The working principle of the boiler is relatively complicated, and it mainly consists of fuel system, flue gas system, and soda water system.
Boiler working principle
- Chinese name: boiler
- English name: boiler
- Definition: Equipment that uses the thermal energy or other thermal energy released from the combustion of fuel to heat water or other working fluids to produce steam, hot water, or other working fluids with specified parameters (temperature, pressure) and quality.
- Applied disciplines: Electricity (level one discipline); Boilers (level two discipline)

- Different types of boilers work differently. According to the size of heating and service objects can be divided into the following 3 categories:
- When the electric boiler reaches the heat storage period, the water supply electric valve will be opened, and the hot water storage tank will start to fill water. When the water level reaches a predetermined high water level, the water supply electric valve can be closed automatically. When the temperature of the hot water storage tank reaches the preset temperature or the end of the heat storage period, the electric boiler stops working at this time. After one minute, the circulating pressure pump starts to stop running, and the circulating pressure pump runs at the set frequency. 30 After a few seconds, the electric boiler runs and starts to store heat.
- Open the electric valve for water supply, close the electric valve for heat storage, start the circulating pressure pump to supply water with frequency conversion and constant pressure, and start the electric boiler after about 30 seconds, so that the water is supplied to the user in a direct supply mode. At the end of the water supply, the circulation pressure pump is stopped first, and the electric boiler is stopped after 60 seconds.
- When the water supply period is reached, the electric boiler water supply electric valve is opened, the heat storage electric valve is closed, the electric boiler is not working, and the circulating pressure pump is frequency-converted to regulate the constant pressure water supply. During the water supply period of the electric boiler, the electric valve for water replenishment is always closed, and no water replenishment operation is performed to avoid supplying cold water to users. If during the heat storage period and the temperature of the hot water storage tank is 5 ° C lower than the set temperature, the circulating pressure pump is put into operation again, and the electric boiler starts to work after 30 seconds.
