Modification and Application of Pulse Soot Blower for 260 t/h Circulating Fluidized Bed Boiler
For coal-fired boilers, the tail heating area ash is inevitable. When the ash is serious, the heat transfer efficiency of the tail heating surface will be reduced, the boiler exhaust temperature will increase, and the boiler efficiency will be reduced; the ash of the heating area will also cause the heating surface to overtemperature and aggravate the corrosion of the heating surface, shorten the life span; when it is serious, it will affect the safe and economic operation of the boiler. The company's 2 × 50MW unit is equipped with DG260-9.81/540-1 type high-temperature and high-pressure circulating fluidized bed boiler. The tail flue is sequentially arranged with double-wound serpentine tube bundle high-temperature superheater, double-wound low-temperature superheater arranged in tandem countercurrent, double-wound triple-tube economizer arranged in tandem and horizontal tandem

At present, there are several types of soot blowing devices for waste heat boilers in the cement industry, and the appropriate soot blowing devices can be selected by analyzing their advantages and disadvantages. 2 The forms and characteristics of several kinds of soot blower 2.1 mechanical vibration dust cleaning mechanical vibration dust cleaning is a traditional dust cleaning method, which is composed of a transmission device, a swing device and a spring anvil assembly device. The drop hammer is rotated by the transmission device. When it rotates to a certain position, the swing device is driven to a certain height by the fork, so that the pendulum falls freely and hits the anvil guide shaft of the spring, at the same time, a suitable vibration frequency is generated, so that the vibration mode of the natural frequency of the water-cooled wall is fully excited, and the maximum vibration frequency is obtained.
