Boiler Operation With Low Furnace Pressure

Our oil/gas fired boilers can be divided into SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above. The fire tube boilers, on the contrary, are intended for use at pressures below 2.5 MPa. Fire tube boilers usually have a capacity of below 20t/h, while water tube ones of 20t/h or more as capacity expansion is possible.

2014-12-25 · A supercritical sliding pressure operation once-through boiler with vertical water wall tubes uses high-cooling-capability rifled tubes for its furnace walls. This type of boiler consists of vertically arranged tubes, instead of a complex spirally wound structure, so that it can improve performance, reliability and economic efficiency.

Properly Diagnosing a Gas Furnace Pressure Switch

Properly Diagnosing a Gas Furnace Pressure Switch

Pressure switches are used in a variety of applications. Generally, they are a normally open switch that closes with either a rise or fall in the pressure it is monitoring, They are used mostly as a safety device, but are also used for operation control, such as fan cycle controls for low ambient cooling, starting and stopping for steam boilers, and the list goes on.
