Boiler for derived fuel RDF, waste plastics RPF and waste wood of combustion of refuses

Abstract

The invention discloses a boiler for derived fuel RDF, waste plastics and waste wood of combustion of refuses, mainly comprising a hearth, a burnout chamber, a superheater chamber and a rear flue duct, wherein the burnout chamber, the superheater chamber and the rear flue duct are successively connected behind the hearth; a drum is arranged above the hearth, and a reverse chain fire grate is arranged on the lower part of the hearth; slag trapping and ash discharging equipment is arranged below the reverse chain fire grate; the front wall of the lower part of the hearth is provided with a waste wood spray seeding device and a refuse derived fuel RDF and waste plastics spray seeding device which are communicated with the inner part of the hearth, and the waste wood spray seeding device is arranged below the refuse derived fuel RDF and waste plastics spray seeding device. In the invention, the steam produced by using refuse derived fuel RDF, the waste plastics and the waste wood to be combusted in a boiler is used for generating electricity and supplying steam. The invention has the social benefit of saving energy and reducing environmental pollution and has favourable economic benefit.

Description

technical field [0001] The utility model belongs to the field of thermal energy power and environmental protection, and specifically refers to a boiler for burning garbage derived fuel RDF, waste plastics and waste wood. Background technique [0002] In self-provided thermal power plants and industrial production, it is necessary to use the steam generated by the boiler, and the fuel usually used by the boiler is fossil fuel. Fossil fuel is a non-renewable primary energy. Due to the increasingly tight supply of primary energy and the rising price, it has become a major problem that seriously restricts the sustainable development of the national economy. [0003] In order to deal with the shortage of primary energy, to develop the economy and improve people's lives, there is more demand for energy, in addition to strengthening energy conservation and reducing consumption and improving the utilization rate of primary energy, we should also actively strive to seek new energy, w...

If it is discarded as garbage, it will not only waste resources, but also pollute the environment

However, due to the characteristics of low ash melting point, high volatile content, and easy bonding of waste-derived fuel RDF and waste plastic RPF, it is easy to coke and accumulate on the heating surface when the existing boiler is used to burn waste-derived fuel RDF and waste plastic RPF. dust, causing the boiler to fail to operate normally, resulting in a high failure rate and even causing safety accidents
