Embodiment Construction

[0005] In order to use low calorific value fuel, the present invention firstly separates the furnace from the pot so that the inner temperature of the furnace will not be affected by the cold water wall; Pot dust pollution. Its specific technical solution is that a vertical partition wall 5 is provided between the rear arch 2 and the front wall 8 above the reciprocating grate 1 to separate the rear arch and the front wall into a furnace 3 and a flue gas dust removal chamber 9, where The upper part of the partition wall 5 is provided with a flue gas port 6, the upper part of the dust removal chamber 9 is provided with a cyclone dust collector 7, and the lower end of the front wall is provided with a fuel injection port 10 opposite to the front end of the reciprocating grate, and the lower end of the partition wall has a The front arch 4 inclined towards the front end of the reciprocating fire grate forms a fuel inlet between the front oven and the reciprocating fire grate. The...

Abstract

The invention discloses a low heat mass firing boiler. The key points of the technical scheme provided by the invention are as follows: the low heat mass firing boiler comprises a steam producing pan which consists of a reciprocating grate, a front wall and a rear arch, wherein a vertical partition wall is arranged between the front wall above the reciprocating grate and the rear arch; a cavity between the front wall and the rear arch is partitioned into a dust removing chamber and a hearth by the partition wall; a flue gas port is formed in the upper part of the vertical partition wall; a front arch tilting towards a feed opening at the lower end of the front wall is arranged at the lower end of the vertical partition wall; a fuel inlet is formed between the lower end of the tilt front arch and the reciprocating grate; and a pipe is arranged between a gas inlet of the steam producing pan and a dust remover outlet at the upper part of the dust removing chamber, a pipe arranged between the gas inlet port of the steam producing pan and a cyclone dust collector outlet at the upper part of the dust removing chamber is a heat-insulating pipe. Compared with the prior art, the low heat mass firing boiler disclosed by the invention has remarkable advantages of use of low caloric value fuel and environment friendliness.

Description

Technical field: [0001] The invention relates to a boiler, in particular to a low thermal mass combustion boiler. Background technique: [0002] If the existing boiler uses low-calorific-value fuels, such as straw or organic waste, the use of low-combustion-value fuels is limited because the existing boiler and furnace are integrated, and the temperature in the furnace is affected by the water wall. Invention content: [0003] The object of the present invention is to provide a boiler using low calorific value fuel. The technical solution of the present invention to achieve the purpose of the invention is to include a steam boiler, which is characterized in that: it is composed of a reciprocating fire grate, a front wall and a rear arch, and a vertical partition wall is arranged between the front wall and the rear arch above the reciprocating fire grate The cavity between the front wall and the rear arch is divided into a dust removal room and a furnace. The upper part of...
