What is economiser in boiler?Economizers, in steam power plants , used to capture the waste heat from boiler flue gas and transfer it to the boiler feedwater.What are the types of economisers?There are two main types of economizers: non-condensing economizer and condensing economizer. Non-condensing economizers are mainly used because thWhy economiser is used in boiler?Boiler economizer used to improve steam boiler system’s efficiency. Economizer is kind of heat exchanging device. [PDF]The heat pump receives heat from a low­temperature source and rejects it at a higher temperature. The heat pump uses waste heat plus an additional 0.22 million Btu of electrical energy to provide 1 million Btu of useful heat, while the boiler requires an input of 1.25 million Btu to provide 1 million Btu of steam heat.

Economizer Functions In Boiler System,Economizer for hi

Boiler economizers reuse exhausted flue gas to pre-heat the feedwater entering the boiler. Essentially a mini-heat exchanger, economizers improve boiler performance while increasing fuel efficiency. By rapidly increasing feedwater temperature through captured flue gas, economizers also provide a significant improvement in steam generation and response time.

Boiler Economiser : Definition, Function & Types

The function of Boiler Economiser. 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.

Waste Heat Boiler - an overview | ScienceDirect Topi

Process heat recovery boilers, or waste heat boilers, are widely used, particularly on ethylene and ammonia plants and on sulfuric acid and nitric acid plants. This type of boiler has developed as a cross between a conventional shell-and-tube heat exchanger and a firetube boiler. Its original function was to cool high temperature process gas and,

Waste Heat Boilers & Sulfur Condensers | Exchang

As it recycles some of the energy used, a waste heat boiler, or waste heat recovery boiler, can reduce the fossil fuel consumption and financial running costs of a system. This also means fewer greenhouse gases are released into the atmosphere.
