Boiler Economizer Efficiency Types And Calculation

Working Of Boiler- Parts, Efficiency, Classification And …

Economizer It is used to increase the efficiency of the boiler as the flue gases from the boiler is made to flow through the economizer before releasing it to the atmosphere. Air preheater It is also used to increase the efficiency of the boiler by preheating the air.

Guidelines for Industrial Boiler Performance …

Boiler efficiency losses arise from four major sources: 1. Heat carried away (out the stack) by the hot flue gases. This loss is usually called "dry flue gas" loss. Hotter stack tem- peratures and larger quantities of excess air increase this loss. 2. Latent heat

Boiler Economizer Types And Efficiency Calculation--ZBG

There are 2 types of condensing economizers: heat exchanger and direct contact (spray). They capture much more heat and therefore can raise the overall boiler efficiency by 10% to 15%. For condensing economizers to be the most effective‚ low temperature heat sinks are required to bring the flue gas temperature well below the flue gas condensing temperature.

A. Economizer The exhaust gases that are leaving the Boiler contain both sensible heat and latent heat. Sensitive heat is the amount of heat needed to raise the temperature of water under constant pressure without changing the liquid state, while Latent heat is required to change Liquid state to the Vapour state at constant temperature and pressure.
