我厂有各种燃煤炉8只,全年生产上耗煤约600～800吨,这些燃煤炉普遍存在耗煤量大、热效率低、烟尘严重等缺点。同时,我厂的生活用煤全年约100吨左右,主要用作0.2m~3立式锅炉烧浴水与蒸饭等。而在生产上的余热却没有充分利用,造成能源的较大浪费。为此,我们决心分三期工程逐步解决这一问题。第一期工程对0.2m~3立式锅炉实行明火反烧法,锅炉上改装抽板式顶煤器装置;同时加装了余热器、除尘器、吸风机。经测定,烟尘的排放达到了国家标准。第二期工程把各自排烟的3台锻工炉改为除尘后集中排烟,建造地下烟道。为充分利用余热,在烟道口安装了锅炉用SW型2吨余热器。为便于排烟,安装了Y6-30-11型锅炉离心引风机。在出烟口建造了16m~3冲击水浴除尘室和ф0.45m×14m的烟囱。
I plant a variety of coal-fired furnace 8, the annual coal consumption of about 600 to 800 tons of production, these coal-fired furnace prevalence of large coal consumption, low thermal efficiency, serious smoke and other shortcomings. At the same time, the life of our plant is about 100 tons of coal throughout the year, mainly for 0.2m ~ 3 vertical boiler bath water and steaming rice. In the production of waste heat is not fully utilized, resulting in greater waste of energy. To this end, we are determined to gradually solve this problem in three phases. The first phase of the implementation of open fire 0.2m ~ 3 vertical boiler anti-burning method, the boiler modified pumping plate top coal device; the same time the installation of a residual heat, dust collector, suction fan. The measured emissions of soot reached the national standard. The second phase of the project to smoke their 3 forging furnace replaced by centralized smoke exhaust, the construction of underground flue. To make full use of waste heat, installed in the flue pipe SW 2 tons of waste heat. In order to facilitate the smoke, installed Y6-30-11 boiler centrifugal fan. In the smoke mouth built 16m ~ 3 impact water bath dust chamber and ф0.45m × 14m of the chimney.
