Design of a Residential Boiler Room.
Abstract：Boiler plays extremely important role in people's production and life, both residents of heating in winter, hot water of life in the family and hotel, gymnasium, fitness center in the building or factory production provides power and heat, boilers need to provide heat.
This design for a residential area of the boiler room design. In this paper, the principle and design basis of the boiler room design are described, and the heat load, the water circulating system and the flow rate and the diameter of the boiler are calculated. The calculation of the fuel combustion, the calculation of heat balance and the calculation of the air resistance of the boiler are carried out. Calculate the maximum heat load of boiler 10.6MW,boiler water circulation 158.4t/h, boiler heat loss 17.109%, send flow fan 2.44m3/s pressure 208.03pa cited flow fan is 2.52 m3 / s, the pressure is 6112.46pa and chimney height to 45m. According to the design and calculation results, the boiler room system composed of three DZL4.2-0.7/95/70-A boiler is given, and the reasonable choice of the blower and pump is given. In addition, the boiler room water hardness does not meet the boiler feed water requirements, need to soften the treatment. According to the calculation of the supply water flow, the design of the three models of the LNN-1200/20 no top pressure fixed bed current regeneration ion exchanger.
