Loosing pressure on heating system with an ideal boiler. Unable to find any leak on the system. Ideal sent an engineer but he claims there is nothing wrong with the boiler. I have isolated the system from the boiler with the isolation valves and still loose pressure (1 bar in a week). On reconnecting the system to the boiler, the pressure

Most sites have a pipe network supplying steam at three or more pressure levels for different pro-cess uses. A typical steam system is illustrated inFigure 3.2. Boiler feed water at high pressure is preheated and fed to boilers where high pressure steam is raised and superheated above the dew point to allow for heat losses in the piping.

Answer (1 of 2): The water is generally pumped to the drum by pumping it using feed pumps at pressures slightly higher than the drum pressure. This is because the drum is already under high pressure. Hence the input fluid must force through this existing pressure and to do so it must be at higher

Waste heat boilers utilise the heat in flue gases from combustion processes or hot waste air flows from industrial processes to generate hot water or saturated steam. Due to economic and legislative considerations, waste heat boilers are frequently used in conjunction with gas turbines and combined heat and power units.

Draft - Draft is the negative pressure (vacuum) of the flue gas measured at any point in the boiler, expressed in millimeters of water column (kilopascals). Economizer - A series of tubes located in the path of the flue gases. Feedwater is pumped through these tubes on its way to the boiler in order to absorb waste heat from the flue gas.
