Embodiment Construction

[0089] The present invention will be further described in conjunction with the accompanying drawings of the above-mentioned embodiments.

[0090] Such as figure 1 , 3 Shown, the industrial boiler of the present invention, kiln double swirl combustion device, comprise combustion hearth 12, fire grate 8, coal inlet 13 and high-temperature gas outlet 15, the top of its furnace hearth 12 cross-sections is to form double swirl The semicircle and double arches of the flow combustion areas 3 and 5 are equipped with tubular combustion air outlets 11 and 6 leading to the furnace on both sides of the furnace. A turbulent combustion zone 14 is provided between the high-temperature gas outlet 15 .

[0091] The working principle is as follows: figure 2 As shown, during the combustion operation, the combustion-supporting air is tangentially injected into the two swirl combustion zones from the combustion-supporting tuyeres 11 and 6 on both sides of the furnace at a certain speed, and th...

Abstract

The invention discloses a double-vortex combustion device of industrial boiler and cave furnace, which comprises the following parts: combustion hearth, stoker, stoke hole and high temperature gas outlet, wherein the hearth traverse section is double-arch to form double-vortex combustion region; the combustion-supporting tuyere on each side of hearth had better tangent the arch, which can extend turbulence combustion region between hearth and high temperature gas outlet in connection with hearth rear. The device is fit for changing the present industrial boiler and cave furnace, which can be applied in the other heating domain.

Description

technical field [0001] The invention relates to an improved coal-fired combustion device, which is mainly used in industrial boilers and kilns, and belongs to thermal facilities. Background technique [0002] Today, no matter how highly civilized and developed human society and science and technology are, people are helpless when faced with the problem of energy depletion. So far, there is no new technology available to solve the problem. this problem. [0003] The report released by the United Nations on January 24, 1994 announced to the world that based on the proven global mineral reserves plus the possible increase in reserves, oil can still be mined for 75 years, natural gas can only be mined for 56 years, and coal can be mined for 42 years. Coupled with the rapid growth of the world's population and the continuous improvement of living standards, this mining life will decrease by a certain percentage. Therefore, in the second half of the 21st century, that is, after 2...
