Automatic supplementing, classifying and grate-firing straw bundle combusting boiler

Abstract

The invention discloses an automatic supplementing, classifying and grate-firing straw bundle combusting boiler which comprises a boiler body, an air distributing unit, a water circulating unit, a smoke discharging unit and a control unit. In work, a straw bundle is placed on a first combusting platform through a feed port, an electric heating bar is heated to a certain temperature, then the strawbundle is ignited, the air distributing unit introduces the air heated by an air preheater into an inner cavity of the boiler body through an air distributing nozzle, ash generated by combustion of the straw bundle falls into a second combusting platform to continue to be combusted, the high-temperature smoke generated by combustion exchanges heat with the water circulating unit and is then guided out under the effect of an induced draft fan, part of the smoke enters a smoke analyzer through a smoke sampling pipeline, the rest of the smoke enters a water film dust removal device, the purifiedsmoke is discharged out of a chimney, a water circulating layer of the water circulating unit can absorb the heat of the high-temperature smoke, a water outlet water pool can convey circulating waterinto the water circulating layer, and the circulating water subjected to heat exchanging flows back to a cooling water pool.

Description

technical field [0001] The invention relates to the technical field of new fuels, in particular to an automatic feed-replenishment graded layer-fired straw-bundled boiler. Background technique [0002] Energy is closely related to people's daily life and the development of society. Sufficient energy is the basis for supporting the rapid development of society. With the gradual reduction of the earth's energy reserves and the huge damage to the environment caused by the use of fossil energy, finding new clean energy to replace fossil energy has become an important goal of global sustainable development. [0003] Biomass energy, as a resource-rich renewable resource, can effectively alleviate the current energy shortage problem. However, the traditional direct combustion method has low combustion efficiency and high pollutant emissions have caused certain impacts on the environment. Although straw briquette fuel solves the problems of difficult transportation and low energy d...

Problems solved by technology

[0004] Although there are various types of straw baling boilers on the market, their design and manufacture are based on other existing boilers and are modified on the basis of them. The existing technology lacks a combustion mechanism for straw baling. Therefore, it is necessary to study the combustion characteristics of straw bales and the influence of various factors on the combustion efficiency and emissions of straw bales. Boilers are critical
