Working of Boiler – Explanation, Parts, Working Principle

The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.

BOILER AND HEATER OPERATIONAL CONTROL

BOILER AND HEATER OPERATIONAL CONTROL. Previously, this guidebook explained why it is necessary to operate a boiler with more air than is theoretically needed to burn all the fuel. Burner controls are therefore always set to provide some amount of excess air in all operating scenarios, typically from two to five percent O 2 in the flue gas.

Hot Water Heating Boiler Operation Details - 39 steps in

On a typical oil fired heating boiler in the U.S. the wall thermostat is controlling the hot water circulator, turning it on or off. It is the temperature of the water circulating through the system (sensed at the primary control on the heating boiler) that actually turns the oil burner on or off to re-heat the water.

Boiler Operation Sequence - Fix it with our Plumbers Fault

Boiler logs are the best method to assure a boiler is receiving the required attention and provide a continuous record of the boiler's operation, maintenance and testing. Because a boiler's operating conditions change slowly over time, a log is the best way to detect significant changes that may otherwise go unnoticed.

The continuous blowers are a part of the standard equipment in the boiler system, which have a capacity starting from 1,600 kg/h or higher and serve as a heat exchanger at 50 kW. The electromagnetic valve and feed water pump are interconnected, thereby blowing is only performed when water is supplied, which increases the heat absorption rate.

The boiler is taken out of operation. The installation should be refilled. Air purge program: After the installation has been refilled and if the pressure was below 0.5 bar the air purge program will start. This will last for approximately 7 minutes. Water pressure is too high (> 3.0 bar): The boiler is taken out of operation.
