Method and apparatus for burning pulverized solid fuel |
摘要 |
A process and apparatus are described with which pulverized coal can be burned with an essentially non-turbulent flame in which the residence time of individual cool particles within the burner flame is generally increased. Pulverized cool is supplied through a plurality of annularly-distributed conduits. A supply of secondary air is passed around the conduits in a manner so as to produce an axial or low turbulent flow of air from the burner with a relatively small amount of the combustion air being swirled to produce a vortex suitable to anchor the burner flame. The pulverized solid fuel is injected to enter both the vortex and flame regions so as to expose a large portion of fuel particles to a low turbulent diffusion flame in which oxygen reaches burning particles primarily by way of a diffusion process.
