Some boilers and waste heat removal equipment in the installation of equipment after use, may affect the normal operation, in order to overcome 4t / h in a small boiler furnace F plus after removal equipment and waste heat utilization equipment caused by dust after adding equipment and waste heat utilization equipment, etc. caused by inadequate pumping power, furnace and other effects appear positive and normal operation of the boiler combustion phenomenon, so the design and manufacture of Y6 ~ 30 ~ 12 wind turbines with a high pressure boiler, high efficiency. The product is also suitable for other similar occasions the use of performance requirements, the product has lost 3.5C, 4.3C, 4.8C, 5.4C, 6.5C, 7.5C, 8.6D seven kinds of machine numbers, except for 8.6D using direct coupling Union, the remaining numbers are used V-belt drive machine.
