China Manufacture Gas Boiler Components Economizer For Steam Boiler economizer for boiler
The function of Boiler Economiser
1. The Economizer in Boiler works on the principle of Heat Transfer. Heat transfer usually takes place from high temperature to low temperature.
In the case of Boilers, flue gases or exhaust from the boiler outlet are at high temperature and water that needs to be preheated is at low temperature.
2. So, this temperature difference between water and flue gases helps to increase the feed water temperature.
3. Depending on the type of operations, design of Economisers can be smoke tube type or water tube type.
4. In smoke tube type flue gases are inside the tubes and water is on the shell side while in the water tube type, water is in the tube and flue gases are on the shell side.
Garbage Incinerator Economiser Definition
1. Boiler Economiser ( Sometimes Called Economizer ) is the Energy improving device that helps to reduce the cost of operation by saving the fuel.
2. The economizer in Boiler tends to make the system more energy efficient.
3. In boilers, economizers are generally Heat Exchangers which are designed to exchange heat with the fluid, generally water.
Boiler Economiser and Waste Heat Recovery Concept
1. Boilers are generally designed to produce steam from water. Water is converted to steam by transferring both sensible and latent heat.
2. Sensible heat is the amount of heat required to increase the temperature of water at constant pressure without changing its liquid state, while Latent heat is the amount of heat required to change the state from Liquid to Vapor at constant temperature and pressure.
3. The exhaust from the boilers is generally in the temperature range of 200°C – 250°C, so there are a huge amount of losses from the boiler if any heat recovery devices are not installed after it.
4. If the exhaust gases which are leaving the Boiler at such high temperature is made to pass through the Economiser in order to provide the required sensible heat to the water by increasing its temperature, it will reduce the heat load on the boiler to the greater extent.
