1.2.2 Heat recovery and/or combined heat and power boilers shall not be included in the boiler plant capacity calculation unless they can operate with their own burners independent of the device from which heat is being recovered. 1.3 Boiler System Capacity: 1.3.1 The boiler system shall be capable of supplying the minimum demand with the
Introduction. Fire tube boilers, also known as smoke tube boilers, are the most common type of industrial boiler employed today. Compared to water tube boilers, they are much more suitable for smaller plant applications because they can better cope with sudden high demand steam fluctuations.. Combustion occurs within a furnace with the exhaust gasses (flue-gasses) passing through a series of
conversion of feed water at inlet temperature to steam, is considered for heat output. In case of boilers with intermittent blowdown, blowdown should be avoided during the trial period. In case of boilers with continuous blowdown, the heat loss due to blowdown should be calculated and added to the heat in steam. 1.6.3 Boiler Efficiency by
The double fire-tube boiler with water-cooled reversal chamber and burner penetration has a capacity of 70 t/h and pressures of 0.5 to 40 bar (g). As hot water boilers, the capacity is between 0,5 and 44 MW. The design temperature for the hot water boilers can be up to 200 ºC. To achieve better efficiency, an economiser can be installed.
