Type Of Boilers

2016-03-09 11:55:45

A boiler refers to a closed vessel in which steam is produced from water by burning fuels. And industrial boilers are used in many applications such as in power plant, in sugar industry, in textile industry, in paper-making and in chemical industry. In general, boilers are classified in two types: fire tube boiler and water tube boiler.

1. Fire tube boiler:

In this types of boiler, water flow surrounding the tubes and the hot flue gases flow through the tubes. The heat passes form the tube to surrounding water which is used to heat the surrounding flowing water and convert it into steam.

ZG Group provides three-pass wetback packaged fire tube boilers using natural gas, light diesel oil, city gas, heavy oil as fuel. WNS series is a typical type of fire tube boiler.

2. Water tube boiler:

In this type of boiler, water flow through the tubes which are surrounded by hot flue gases. This flue gases used to heat the water and convert it into steam.

Compared with fire tube boilers, water tube boilers have a wider capacity range and application range. Most of the industrial boilers are designed as water tube type. ZG Group provides water tube boilers burning coal, gas, biomass, oil, waste heat. Typical types are SZL series Coal and Biomass Fired Boiler, SZS series Gas and Oil Fired Boiler, CFB Boilers, Waste Heat Recovery Boiler.
