1问题的提出现今铁路基层单位较多使用的锅炉为0．5T-4T燃煤蒸汽锅炉,其燃烧方式为使用一台鼓风机、一台引风机和链条炉排联合调节燃烧强度。由于不同煤质需要风道内单位时间供风量有所不同,有时还需要调节炉排走行速度,才能达到最佳燃烧效果。而调节单位时间内的供风量过去的旧式调节方法是通过调节风道闸门开度,这种调节方式在闸门未全开的情况下,存在电能浪费现象。如果
1 PROBLEM PROBLEM Presently, most of railway grassroots units use 0.5T-4T coal-fired steam boilers, and their combustion method is to use a blower, a draft fan and a chain grate to jointly adjust the combustion intensity. Due to different coal needs air duct unit time for the air volume is different, and sometimes need to adjust the grate walking speed, in order to achieve the best combustion results. The regulation of air supply units within the time the old way of regulating the past by adjusting the air duct gate opening, this regulation in the case of the gate is not fully open, there is a waste of energy phenomenon. in case
