Gas Fired Water Tube Boilers 15 t/h Operating Pressures of 17bar

ZBG is a leading industrial boiler manufacturer, supplier and exporter, which has offered all types of boilers to over 30 countries and regions in the world. Among the 9 series of products, gas and oil fired boiler is a typical product, including WNS series, SZS series, ZWNS series, ZG series, etc. The SZS series gas and oil fired boiler is D type, water tube, double-drum industrial boiler, ranging from 4 ton to 35 ton, firing natural gas, coke oven gas, light oil, heavy oil, LPG, diesel oil, etc.

15 t/h gas fired water tube boiler operating pressure of 17 bar

Recently a customer inquired of 15 t/h gas fired water tube boiler operating pressure of 17 bar, and our engineer recommended the SZS series water tube boiler, 4 ton - 35 ton, up to 38.2 bar. Compared to fire tube boiler, a water tube boiler is safer by design and generally can operate many years longer than firetube boilers. Watertube boilers are available in larger capacities and recover faster than firetube boilers. Watertube boilers can also handle higher pressures, and have the ability to reach very high temperatures with the use of superheaters. The 15 t/h gas fired water tube boiler is planned to supply heating for a large five-star hotel.

Water tube boiler advantages:

Savings in weight of about 3:1 for a comparable heating surface area
Possibility of using higher temperatures and pressures without unduly increaseing wall thicknesses increases plant efficiency.
More efficient combustion space allowed
Greater flexibility of the structure and rapid circulation prevents the problems of thermal stressing in the tank boilers which leads to grooving. In water tube boilers roof and floor tubes are sloped at 15' to ensure circulation
thinner tube materials allow rapid steam raising and faster heat transfer rates
Saving in space for sam steaming rate
Wider safety margings- limited tube diameters and protected drum surfaces mean failure in tubes releases a flow of steam dependent on tube diameter
Thin tubes are easier to bend, expand and bell mouth
