For every enterprise used in the construction of hot water boilers, due attention must be paid to all aspects of heating quality and management for its livelihood and development. As long as the interests of all parties are coordinated, the company can develop and better serve. What should be done before starting the hot water boiler construction for the new equipment? We’ll sort out some notes for you.
Hydraulic testing checks the tightness of pressure parts. The purpose of hydraulic testing is to check the strength and tightness of pressure parts. The newly installed boiler shall be overtested at 1.25 times operating pressure. Typically, after checking the pressure component, for example, replacing or repairing some valves, boiler tubes, manifold, etc., and after making minor repairs to the boiler, an operational pressure test is performed.
For auxiliary equipment testing and verification of each electric door and damper, the hot water boiler construction cannot be stopped, so many companies will be equipped with boiler auxiliary equipment, so auxiliary equipment can better test and verify each electric door and damper. Main power emergency service.
Remove water from the walls and boiler tubes. Allow the boiler to reach a certain depth of drilling, to avoid avoiding the boiler wall during boiler operation, and the formation of cracks in the furnace wall after sudden heating and uneven heating. The strength of the furnace and the ash joint on the furnace wall are relatively good, and the furnace wall is resistant to high temperature. Talent.
Under the furnace temperature, the pressure is determined by the burner, and the burner manufacturer knows which device belongs to. The pressure in the furnace is active, and the pressure and temperature are still low. As a result of the hot water boiler structure furnace temperature is different, the burner structure is different, the choice of materials are different. The burner of the furnace chooses high pressure to offset the pressure of the low pressure burner.
When selecting the calorific value of the gas as fuel, because the calorific value of the various gases is different and the pressure is not consistent, what is the amount of heat to choose when selecting the burner manufacturer of the fuel burner, calorific value, and the pressure to choose the right burner to prevent the risk of incorrect picking.
