Abstract

The invention relates to a clean coal-burning vacuum boiler, belonging to the technical filed of a vacuum boiler. The invention comprises a boiler body, a drum and a grate. The drum is arranged at the upper part of the boiler body and the grate is arranged at the lower part of the boiler. A burning chamber is arranged at the middle part of the boiler body. The invention is characterized in that the front part of the burning chamber of the boiler body is provided with a gas generation chamber; the upper part of the gas generation chamber is provided with a gas outlet; the gas outlet is communicated with the upper part of the burning chamber; the gas generation chamber is communicated with the lower part of the burning chamber and is provided with a fixed grate; an exit of the burning chamber is provided with a dedusting water-cooling pipe bank; and the two sides of the burning chamber are provided with a boiler lateral water-cooling tank. The invention has the advantages of increasing the coal burning efficiency, saving the energy resource, realizing smoke eliminating and dust removing effects, decreasing the atmosphere environmental pollution, economy and environmental protection, etc. The invention can be widely used in the coal-burning vacuum boiler industry.

Description

technical field [0001] The invention belongs to the technical field of vacuum boilers, in particular to a clean combustion coal-fired vacuum boiler. Background technique [0002] At present, in the field of vacuum boilers, fuel oil (gas) is mainly used as the main fuel for boilers, but with the increasing shortage of petroleum energy and the continuous rise of petroleum prices, the operating costs of boilers are increasing day by day. Inexpensive coal has become the main fuel for boilers, but the environmental pollution caused by coal combustion is well known. The traditional way of coal combustion is that coal is on the chain grate, and the coal is ignited from the upper part. During the combustion process of coal, a large amount of Dust and harmful substances such as nitrogen oxides, sulfur dioxide, carbon dioxide, etc., some of which are black smoke due to incomplete smoke from coal combustion, causing serious pollution to the atmospheric environment.
