一、前言造纸工业是一个用汽负荷不均衡的企业,对于年产量为50kt 级的中型造纸厂,全厂最大用汽量每小时可达17～18t,而最小用汽量可能只有2t/h 左右。尖峰负荷一般要达最小负荷的8～9倍,这种不稳定的运行负荷,会造成锅炉热效率降低。为了消除供汽锅炉负荷的波动,稳定供汽压力,提高锅炉的运行效率,可在供汽系统中设置蒸汽蓄热器,使锅炉连续地 I. INTRODUCTION The paper industry is a company with unbalanced steam load. For medium-sized paper mills with an annual output of 50 kt, the maximum steam consumption of the whole plant can reach 17 to 18 tons per hour, while the minimum steam consumption may be only 2t/h. about. The peak load is generally 8 to 9 times the minimum load, and this unstable operating load will cause the boiler thermal efficiency to decrease. In order to eliminate fluctuations in the steam supply boiler load, stabilize the steam supply pressure, and increase the operating efficiency of the boiler, a steam accumulator can be installed in the steam supply system to make the boiler continuously
