A boiler is a combustion system that is self-contained and heats water. The heated water turns into steam and is then used by the operator. In order to have an efficient working unit, there are four parts to the system. Here is a short explanation of what each part of a boiler does.
The boiler system can be filled with corrosive gasses that can affect the life of the boiler. The deaerator pumps can help minimize the impact of the gasses. By raising the temperature of the water feed, you can also prevent thermal shock. By reducing the corrosive gasses and thermal shock, you can prolong the life of your boiler system, save energy, and lower operating costs.
Without combustion, there would be no heat, and for that reason, the reactions that occur within the combustion chamber are critical to the effectiveness of the boiler system. Boilers are created of cast iron, a sturdy and heat resistant metal that can withstand the incredible temperatures that the burning fuel reaches inside the combustion chamber. Once ignited, the temperatures can move up 200 degrees or more in minutes and then the system can efficiently transfer the heat into the exchange unit.
As the name suggests, the burner heats the water causing the combustion to occur. As the reaction moves inside the unit, the thermostat sends a message to either produce more heat or to stop burning. An external source provides the fuel, which is pumped through a specially designed filter into the boiler through a nozzle that initiates a fine spray. The mist allows for easy ignition.
In a boiler unit, the exchanger is the part that moves the pressurized, heated water through a system that transfers the heat to an object or into the air and recirculates the water.
It is surprising that so many people know so little about such a common and useful machine. How much did you know about the workings of the boiler?
