* at present, there are many boiler series, but coal quality varies from one to another, plus after installing the dust-removal equipment and waste heat utilization device，it creates in sufficient drawing force which influences its normal running.in order to overcome the drawing force shortage caused by the above mentioned reasons; positive pressure occurring in the furnace, which influence boiler combustion and normal running, thus it designs and manufactures this induced draught fan for consumers’ selection and application.
