Multifunctional wood and coal furnace capable of preventing fire bar melting

Abstract

A multifunctional wood and coal furnace capable of preventing fire bar melting comprises fire bar supporting water pipes (1), heat absorption vertical pipes (2), a rotary valve (3), heat absorption fins (4), movable fire bars (5), a heat absorption box (6) and U-shaped grooves (8). The fire bars (5) are arranged on the lower portion of a hearth. The heat absorption fins (4) are arranged in the heat absorption box (6). The multifunctional wood and coal furnace is characterized in that the two furnace leg fire bar supporting water pipes (1) are horizontally arranged on the lower portions of the fire bars (5), one U-shaped groove (8) is formed at each of the two ends of each fire bar supporting water pipe (1), the set of fire bars (5) are correspondingly arranged on the two U-shaped grooves (8), the four to six heat absorption vertical pipes (2) are longitudinally arranged around the hearth, and the rotary valve (3) is arranged on the smoke outlet portion of the hearth. The multifunctional wood and coal furnace has the beneficial effects of being high in thermal efficiency and capable of preventing the fire bars from being molten at the high temperature.

Description

technical field [0001] The invention relates to a heating stove, in particular to a firewood-coal multifunctional heating stove which prevents furnace bars from melting. Background technique [0002] Due to the backward technology of traditional heating furnaces, the thermal efficiency is very low. The specific shortcomings are as follows: 1. The current furnace bars all use two groups of movable furnace bars linked together, without anti-melting protection measures. The furnace bars are in a high temperature state for a long time. It is easily melted by high temperature. 2. The heat absorption efficiency of the furnace and heat-absorbing fins is low. 3. The valve design of the flue opening is not scientific and reasonable enough. Contents of the invention [0003] In order to solve the defects of the traditional heating stove, the present invention provides a firewood-coal multifunctional heating stove with simple structure and low cost to prevent furnace bars from melt...
