A water vapor combustion device

Abstract

The invention discloses a steam combustion-supporting device. The steam combustion-supporting device comprises a water tank arranged outside a furnace body of a combustion furnace, wherein a connection water jacket communicating with the water tank, and a plywood box arranged between the connection water jacket and the furnace body, and used for generating steam, are arranged at the outer side of the lower part of the furnace body; a water inlet tube and a connection tube are arranged on the plywood box; the connection water jacket communicates with the lower middle part of the plywood box through the water inlet tube; a gas inlet port of the connection tube communicates with the top of the plywood box, and a gas outlet port of the connection tube is arranged above a liquid level in the water tank; and a gas outlet tube is arranged at the top of the water tank, a hearth is arranged in the furnace body, and the tail end of the gas outlet tube communicates with the hearth. The steam combustion-supporting device disclosed by the invention is simple in structure, novel in design, convenient to produce, wide in application range, high in practical value, abundant in steam supply, high in fuel utilization rate, good in heating effect, and low in smoke and dust emission; and energetic promotion is necessary.

Description

technical field [0001] The invention relates to a combustion-supporting device, in particular to a steam combustion-supporting device. Background technique [0002] Due to the limitations of the combustion furnace itself, insufficient fuel combustion often occurs during use, resulting in a large amount of black smoke and carbon monoxide, resulting in low fuel utilization and environmental pollution. [0003] In order to improve fuel utilization, steam-supported combustion has been used in the field of combustion furnaces. The use of steam-assisted combustion is to introduce high-temperature water vapor into the furnace. The water vapor undergoes a chemical reaction under the action of the high temperature of the furnace to decompose water into hydrogen and oxygen. Make black smoke and carbon monoxide burn again, hydrogen is a combustible gas, which can effectively improve the utilization rate of fuel to make it burn more fully, and also reduce the emission of smoke and dust....

AI Technical Summary

Problems solved by technology

[0004] However, the current steam combustion-supporting device must additionally add a steam generating device or directly feed oxygen and hydrogen into the furnace, so that the additional investment is large, and the cost is increased, and the gain outweighs the gain

Moreover, the use of steam for combustion in the market still has the problems of poor heating effect and insufficient steam supply.

There are also some combustion-supporting devices that will bring in a large amount of liquefied water when the steam is passed into the furnace, resulting in more water and less steam passing into the furnace, and the combustion-supporting effect is severely limited.
