ZBG’s 12 ton gas steam boiler with pressure of 7-8kgs adopts water tube packaged type, which can be used in many industries, like the Hospitals, Universities, Universities, Manufacturing and processing facilities, Utilities, Petrochemical, Pulp and paper, Pharmaceuticals, etc.
The water tube gas boiler uses membrane water wall structure, furnace wall water cooling includes not only the side walls, roof and floor, but the high-duty rear wall as well – eliminating refractory and its inherent maintenance. This unique boiler feature locates total water cooling where it can contribute most to keeping maintenance costs down. Each rear wall tube is a single flow path between drums to assure proper circulation and cooling. And the gas-tight setting membrane provides the gas-tight setting absolutely necessary on all package boilers. This construction uniquely inhibits dew-point sulfur corrosion and outages caused by gas leaks. ZBG’s membrane water walls use large diameter tubes and small membrane spacing that provide the best combination of heat transfer efficiency and maintenance accessibility.
In water tube boiler, boiler feed water flows through the tubes and enters the boiler drum. The circulated water is heated by the combustion gases and converted into steam at the vapour space in the drum. These boilers are selected when the steam demand as well as steam pressure requirements are high as in the case of process boiler / power boilers.
Most of large scale boilers are designed as water tube boilers, ZBG provides types of water tube boilers, the SZL series coal and biomass boiler, SZS series gas and oil boiler, SHX series CFB boiler, waste heat recovery boiler. Contact us for more water tube boiler information and price list!
