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.
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.
The standard cold water operating pressure of most US and Canadian hot water boilers is If the boiler pressure drops below 12 psi the valve will allow new water into the unit to bring up the pressure reading Standard Hot Operating Pressure
Steam boiler is dangerous machinery and for that reason law is required to control every aspect of the boiler Factories & Machinery (Steam and Unfired Vessel) Regulations 1970 provided stringent requirement on safety aspects and controls on This Code stipulates that any boiler should consolidate thirteen essential fittings so that can [ ]
· In any event the usual cold pressure of a boiler should sit at Most pressure gauges display different-colored zones If the needle sits much outside the green zone particularly on the high side you have a problem Pressure Change Range Pressure will change when the unit fires up the heat
Typical pressure for a residential boiler serving a two story home would show 12 psi cold and less than 30 psi hot Over 30 psi boiler pressure will cause the pressure relief valve to open Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F
