蒸汽蓄热器是一种有效的节能设备,在日本等发达国家业已广泛使用。在我国起步较晚,本文根据工厂实际情况,进行分析比较,提出设计方案,并于85年设计制造了36m~3蓄热器,当年投运。经锅炉热平衡测试,锅炉热效率在用蓄热器之后提高5.7％,与此同时改善了锅炉的燃烧工况,满足了锻造生产的特殊要求,改善了生产环境,减轻了工人的劳动强度,取得了明显的综合性效益。本文根据运行情况,还提出必须加强给水除氧工作,以便防止蓄热器腐蚀,延长其使用寿命。
Steam accumulator is an effective energy-saving device, which has been widely used in developed countries such as Japan. In our country started relatively late, this article according to the actual situation of the factory, carries on the analysis and the comparison, proposed the design plan, and in the 85 years designs and manufactures the 36m ~ 3 regenerator, then put into operation. After boiler thermal equilibrium test, the thermal efficiency of the boiler increased 5.7% after using the regenerator, meanwhile, the combustion conditions of the boiler were improved, the special requirements of forging production were met, the production environment was improved, the labor intensity of the workers was reduced, Obvious comprehensive benefits. In this paper, according to the operation, it is also proposed to strengthen the oxygen supply to the work in order to prevent the accumulation of corrosion, prolong its service life.
