Dec 07, 2016 · Water tube boilers can operate at pressures up to 5000 psig. Additionally, when used with steam circulating super-heaters, they are capable of reaching much higher temperatures than fire tube boilers. For these reasons, water tube boilers have become the most commonly used boiler type in the modern age.
In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.

A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam.
Boilers are part of a hydronic heating system. Hydronic systems use water to transfer heat to a distribution source, like a radiator, to heat a home. Hydronic systems can heat via hot water or steam, depending on the type of boiler used. The boiler is the part of the system that heats the water to be distributed.
Oct 28, 2013 · Eventually steam is released for use. Water Tube Boilers – In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam.
There are two basic types of boilers: firetube and watertube. The fundamental difference between these boiler types is which side of the boiler tubes contain the combustion gases or the boiler water/steam. Firetube Boiler. In firetube boilers, the combustion gases pass inside boiler tubes, and heat is transferred to water between the tubes and the outer shell.
Which type of boilers apply to this industry? WNS Fire Tube Boiler. WNS series packaged gas and oil fired boiler, three-pass wet-back design, fire tube boiler 1 ton - 20 ton. Request a Quotation Chat online; DZL Series Coal Fired Chain Grate Boiler. DZL series is single-drum fire-water tube boiler.
