vacuum water boiler t6

The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.


water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Aug 13, 2015 · Most boilers are designed for a 20-25 degree temperature rise. If the system return water temperature is 150 degrees F, the supply water temperature to the system from the boiler should be 20-25 degrees F higher. A temperature span greater than the boiler design temperature rise could cause Thermal Shock inside the boiler.

Section 23 52 39 - FIRE-TUBE BOILERS

Connections between tank and heater should be made with copper, brass or iron pipe. Lead pipe is unsuitable for hot water connections, as it expands when heated and upon cooling does not contract to its original length but sags when run horizontally, thus forming traps in the pipe. Furthermore, the joints on lead pipe are liable to be melted and pull apart when the temperature of the pipe becomes very high, or should the water be siphoned out of the boiler …
