Energy-saving and environment-friendly boiler with preheating function

Abstract

The invention discloses an energy-saving and environment-friendly boiler with a preheating function. The energy-saving and environment-friendly boiler comprises a shell, a grate, a boiler slag collection trough, a circulating pump and a fan. A vertical material uniformization plate is arranged on the upper surface of the grate. A material passing opening penetrating the two sides is formed in the material uniformization plate. A heat absorption pipe is arranged in the boiler slag collection trough and is located at the bottom of the boiler slag collection trough, and the outer end of the heat absorption pipe communicates with a heat exchanger. Multiple heat conduction columns are horizontally inserted into a water jacket. The other end of a smoke discharging pipe communicates with a waste heat collection box. A heat exchange coiled pipe is mounted in the waste heat collection box. The bottom of the waste heat collection box communicates with a purification box. According to the energy-saving and environment-friendly boiler, the arranged material uniformization plate moves to uniformly pave dye, the combustion area of fuel is large, and contact of the fuel and air is sufficient; and heat in smoke is absorbed by the heat exchange coiled pipe and used for preheating inner heating water, the water temperature increase speed is increased, and the heating efficiency of hot water in the boiler is guaranteed.

Description

technical field [0001] The invention relates to a boiler, in particular to an energy-saving and environment-friendly boiler with preheating. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. [0003] Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in industrial production. Boilers that generate steam are called steam boilers, often referred to simply as boilers, and are mostly use...

AI Technical Summary

Problems solved by technology

The heat generated by the existing boiler during the combustion process is only absorbed and utilized, and the heat utilization rate is low. Part of the heat in the boiler is discharged with the air, and part of it is stored in the slag. After the heating is completed, the stored heat cannot be used. , followed by the slag discharge, resulting in waste of heat; on the other hand, the flue gas generated during boiler combustion contains a large amount of harmful substances and ash, which will damage the surrounding environment. Therefore, it is necessary to improve the existing boiler
