2015 advanced and energy-saving gas combi boiler

Introduction of gas combi boiler :

1. Boiler is a kind of energy conversion equipment.

2. The chemical energy, electrical energy, high temperature flue gas heat energy which come from the fuel was converted to steam, high temperature water or heat transfer fluid which has a certain energy

3. Boiler was consisted of boiler and furnace.

Function and use of gas combi boiler :

1. The water and steam came from boiler can supply heat for industry and people’s livelihood.  It is also can be converted to mechanical energy by steam power plant.

2.  Hot water boiler (to provide hot water), is mainly used for life. There are also some used for industry.

3.  Steam boiler (to provide steam), is mainly used for coal power stations, ships, locomotive, industrial and mining enterprises. 

4. The main function of boiler is heating, bathing and supply of high quality steam, etc.  The boiler which used for heating and bathing is water boiler. The industry used boiler is steam boiler.

The classification of gas combi boiler : 

1. According to the fuel, there are electric boilers, oil boiler, gas boiler, coal or biomass boiler etc.

2. According to the structure , there are vertical steam boiler, horizontal steam boiler, (small steam boiler are single pass or two-pass  vertical structure ; The big steam boiler are  horizontal structure and three-pass boiler)

Main parameters of gas combi boiler

The major indexes of the performance of the boiler:

Steam boiler:

(1) evaporation capacity (t/h or kg/s)  

(2)pressure of steam  

(3)temperature of steam  

(4)temperature of feeding water

Hot water boiler:

(1) heat power MW  

(2)   hot water pressure  Mpa

(3) hot water temperature  

(4) feeding water temperature
