The method of utilizing hot coal gas as the fuel for thick oil hot recovering steam boiler is that the low heat value hot coal gas the hot coal gas generator generates is dedusted and conveyed to the thick oil hot recovering steam boiler so as to be burnt in the great capacity and low heat value gas combustor while preheated oxygen-rich air is supplied with one oxygen-rich combustion supporting system for high combustion efficiency. By utilizing the hot coal gas as fuel substitute can save petroleum resource and raise the combustion efficiency of hot coal gas.

A yard waste incinerator device is provided. The device includes an at least partially spherical outer member which is comprised of a truncated sphere. The outer member is usually comprised of a multiplicity of frame members that are spaced apart, but intersect with one another so they look much like latitudinal and longitudinal lines of a globe. Thus, they define a fairly open structure. A partially spherical cover is provided that will moveably engage the frame of the spherical outer member. The cover may be removed to allow debris and the like to be placed in the interior of the at least partially spherical outer member. By placing the cover back in a closed position, the yard ball can be rolled from one place to another rather easily. This is the result of the cover being generally spherically shaped, similar to the outer member so that, when the cover is in place, the yard ball has a spherical or ball shape. When the cover is moved, yard debris may be placed into the device.
