Filter plate and heating device with same

Abstract

The invention discloses a filter plate and a heating device with the same, and belongs to the field of civil heating devices, wherein the filter plate comprises uniformly distributed filter holes, the filter holes are suitable for adsorbing flue gas dust and tar in a hearth, the filter plate resists high temperature of the top of a flame area, and the filter plate is arranged at the top of the hearth and located between the upper portion of the flame area and a smoke outlet. According to the scheme, smoke filtering and dust adsorption can be achieved through the arrangement of the filter plate, and secondary combustion can be achieved when tar is adsorbed on the filter plate; due to the fact that the filter plate carries heat, the heat cannot be dissipated too fast in the intermittent feeding process, and the effect of controlling the temperature of the top of the hearth can be achieved; in addition, in the periodic intermittent fuel feeding process, ash removal treatment can be conducted on the filter plate according to needs, continuous and good work of the heating device and cleaning of follow-up pipelines are further facilitated, and the risk of polluting indoor air is further reduced.

Description

technical field [0001] The invention belongs to the field of civil heating devices, and in particular relates to a filter plate and a heating device with the filter plate. Background technique [0002] At present, civil heating furnaces mainly include electric heating furnaces, fuel gas heating furnaces, coal-fired heating furnaces, etc. Among them, coal-fired heating furnaces are economical and affordable. A coal-fired heating furnace with lower heating costs is ideal. [0003] my country has established a complete classification system for coal, including coal calorific value classification, coal phosphorus classification, sulfur classification, etc. Different classifications of coal have different combustion characteristics. There is no record in the prior art of giving different combustion-supporting methods to different coals. In the prior art, a vertical coal-fired atmospheric hot water boiler is mainly composed of a pot shell head, a furnace furnace, a furnace roof,...

AI Technical Summary

Problems solved by technology

[0006] 1. The exhaust path of the flue gas at the top of the furnace through the original exhaust system includes the flue gas dust and tar generated by combustion. The flue gas dust and tar are easy to stick to the inner wall of the furnace or the exhaust pipe, which is not conducive to the continuous good work and follow-up of the heating device. The cleanliness of the pipes also has the risk of polluting the indoor air

[0007] 2. In the process of intermittent feeding, the temperature at the top of the furnace will be lost in a short time, resulting in an unstable temperature at the top of the furnace, which will easily lead to insufficient ignition point of coal-fired gas
