A FURNACE OF A PULVERIZED COAL BOILER FOR POWER STATION

摘要

A furnace of a pulverized coal boiler for a power station is provided to increase heat transmission efficiency by heating a low temperature inner and outer cooling wall with rotating a pipe type flame when a temperature of the flame is a maximum. A furnace(100) of a pulverized coal boiler for a power station includes a furnace wall(110), an outer cooling wall(120), an inner cooling wall(130), and a pulverized coal spray nozzle(140). The outer cooling wall is separately formed inside of the furnace wall along the furnace wall. In an inside of the outer cooling wall, a heat transmission fluid such as water flows therein. The inner cooling wall is formed inside of the outer cooling wall with being separated from the outer cooling wall. The inner cooling wall is installed adapted for an arrangement of a circulation boiler, a pipe boiler, a peripheral structure, and a peripheral water pipe. The pulverized coal spray nozzle plays a role of spraying a pulverized coal in a space to form a combustion room(150) between the outer cooling wall and the inner cooling wall.
