Description

Heating structure convenient for adjusting boiler fire

Technical Field

The utility model relates to a heating structure convenient for adjusting the fire power of a boiler, and belongs to the field of boiler heating.

Background

The boiler continuously heats water in the boiler to generate a large amount of industrial steam by combusting natural gas, and provides energy required for disinfection and sterilization for water production workshops and production workshops. The automatic start-stop combustion of the boiler is realized through two groups of pressure controllers. A group of control boilers start and stop; the other group controls the big and small fires of the boiler to burn; the start and stop states of the boiler are controlled according to the pressure in the boiler, and the pressure relations are as follows: the boiler starting pressure is less than the big fire starting pressure is less than the small fire starting pressure is less than the boiler stopping pressure.

When the boiler is started, firstly, the temperature in the boiler is quickly increased by high-fire combustion, and when the pressure of industrial steam generated in the boiler reaches a set value of low-fire combustion pressure, the boiler is automatically switched to low-fire combustion; when the industrial steam pressure in the boiler reaches a set value of the furnace stopping pressure, the boiler automatically stops the furnace; with the use of workshops, industrial steam in the boiler is continuously consumed, and when the pressure in the boiler is reduced to a set value of starting pressure, the boiler is started again to enter the next cycle.

The boiler pressure setting for the current maximum workshop gas consumption condition is integrated as follows: boiler start pressure: 5.3bar; high fire initiation pressure: 5.6bar; light fire initiation pressure: 6.4bar; boiler stop pressure: 6.9bar; the control program is generally set and not changed after debugging.

According to the equipment use requirement, the furnace of the boiler can be stopped manually and directly, but the furnace is stopped after the furnace needs to be turned to a small fire, so the furnace can be stopped only after the internal pressure of the furnace is 6.4 bar. The gas consumption of the workshop is low or high according to different use conditions, and the workshop can be stopped after the workshop is burnt to 6.4bar when the pressure is low, so that the labor and the energy consumption are wasted.

In order to solve the problems, a group of manual switches and heating structures are led into the large and small fire pressure controllers at present, so that the small fire can be manually switched at any time to burn and then stop the furnace, and the labor and energy consumption cost is saved while the equipment use requirement is met.
