Chain type environment-friendly double-drum biomass particle gasifying burning hot-water boiler

Abstract

A chain type environment-friendly double-drum biomass particle gasifying burning hot-water boiler comprises a furnace, an upper chain grate drum and a lower chain grate drum. A pre-heating burning closed arc-shaped arch, a pre-heating burning net-shaped arc-shaped arch wall, a high-temperature radiation burning arc-shaped arch wall, a high-temperature radiation burning closed top arch connected with the tops of the pre-heating burning net-shaped arc-shaped arch wall and the high-temperature radiation burning arc-shaped arch wall, an arc-shaped smoke return arch and a convection residue-depending burning arc-shaped hearth are sequentially arranged in the furnace from the front. A smoke-return high-radiation inclined elongated heated arch is arranged on the upper portion of the convection residue-depending burning arc-shaped hearth. The upper drum and the lower drum are arranged on the back of the furnace and are connected by a heated pipe beam. Heated water-cooling wall pipes are distributed on two sides of the furnace, and the upper ends and the lower ends thereof are respectively connected with an upper heated water circulating pipe and a lower heated water circulating pipe connected with the upper drum and the lower drum. A high-radiation heated pipe is arranged below the high-radiation heated arch and connected with the lower drum. The chain type environment-friendly double-drum biomass particle gasifying burning hot-water boiler can burn gas and tar sufficiently and overcome the difficulty of blocking of a flue and the pipe beam, and is safe, reliable, energy-saving, environment-friendly and long in service life.

Description

technical field [0001] The invention relates to a boiler, in particular to a chain-type double-drum biomass particle gasification combustion hot water environmental protection boiler. Background technique [0002] At present, with the massive consumption of non-renewable energy such as coal, oil, and natural gas, the shortage is increasing, and the use of traditional combustion methods will also cause environmental pollution. As a renewable energy source, biomass materials are receiving more and more attention from the society, but At present, biomass gasification technology only stays in the use of gasifier to produce combustible gas for daily cooking, which greatly limits the application and development of biomass gasification technology. At present, environmentally friendly boilers burning renewable energy granular biomass are being widely promoted and applied at home and abroad, but the difficult problem for domestic boiler manufacturers to solve and deal with is that th...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is the problem that the new energy biomass particle atmospheric pressure environmental protection boiler and the pressurized hot water steam boiler are burning plant syrup clogging the smoke pipe, which cannot be used normally and prolongs the service life of the boiler. The design technology of the boiler is very scientific. Reasonable
