The heat in the steam produced is about 95% of that lost by the gases passing through the boiler. Heat lost by hot gases = V s ( t 1 − t 2) MJs − 1, where V = m 3 gas/sec, s = specific heat (volume basis). Heat absorbed by water = 0.95 Vs ( t1 − t2 )MJ s −1, t1 and t2 = temperature of hot gases before and after the W.H. boiler, °C.

temperature is held above 190° F there is a potential for feed water pump cavitation. – Temperature gauges fail, so holding the tank at 200ºF. – When the feed water pump comes on, the boiling point of water is reduced – Deareators use head pressure (1 psi for every 2.3 feet of height

When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100°C (180°F) This rise in temperature can be detected and is called Sensible Heat

Steam boilers and waste heat boilers

Jan 29, 2021 · In a reversal of the system inside a fire-tube boiler, waste heat, in the form of hot gases or furnace flames, surrounds the water-filled tubes. Insulating materials are used to protect the boiler tubes against flame damage. As well as tolerating high pressures, a water-tube waste heat boiler can respond quickly to changes in heat input.

Safe management of industrial steam and hot water boilers

Water will be feed through condensate extraction pump (CEP) and condensate water heated in heat exchanger and then goes to deaerator. This water will reduce the fuel consumption and will make system cost effective. KEYWORDS: Waste heat recovery boiler (WHRB), heat exchanger, Condensate extraction pump (CEP), deaerator. 1.
