Talking about the working principle of coal-fired boiler

Boilers use different specific gravity of water. After heating the water inside, the specific gravity of hot water will rise slightly to the upper part, while the specific gravity of hot water will increase and sink after heating and cooling.

Then the cold water inside will be heated by the heating chamber of the boiler, and the water temperature will rise, so that the hot water will enter the radiator at home and then dissipate heat. After heat dissipation, cold water will flow back to the heating chamber of the boiler for heating.

Working principle of circulating pump of domestic boiler: When the domestic heating boiler is used, first turn on the power supply, then adjust the temperature control system, suck the probe on the iron pipe or boiler, and finally ignite the boiler to raise the temperature.

When the water temperature reaches the set temperature, the temperature control lamp lights up, the water pump starts and works, and when the temperature is lower than the set temperature, the boiler circulating pump stops working.
