Water tubes within the boiler's furnace. Water-tube boilers have water-containing tubes heated externally by the fire produced in a furnace that burns gas or another type of fuel. As a result, they produce steam by transferring the heat received to the water circulating inside them. Next, the resulting steam feeds industrial processes downstream.Get Price
Boiler expanders are designed with rolls sufficiently long to roll 1/4" to 3/8" beyond the sheet thickness. Boiler inspectors insist that tubes be rolled the full thickness plus a minimum of 3/16" beyond the sheet or drum thickness to a maximum 1/2".

A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.Get Price
In some steam drum designs, water level is absolutely critical because the baffling could isolate a generating location of the boiler when the steam drum water level drop below a certain mark. Thin-lipped bursts can also happen in superheater tubes if steam flow is inadequate, if deposits restrict flow, or if tubes are closed off by water due Get Price
