Three-dimensional biomass fuel energy-saving boiler

Abstract

The invention discloses a three-dimensional biomass fuel energy-saving boiler. The three-dimensional biomass fuel energy-saving boiler comprises a biomass fuel adding door, a heat exchange stopping rod, a heat exchange furnace body and a heat preservation furnace body; and the heat exchange furnace body is installed in the heat preservation furnace body, a plurality of heat exchange fins are welded to the outer wall of the heat exchange furnace body, the heat exchange stopping rod is welded to the inner wall of the heat exchange furnace body, a burning hearth is arranged inside the heat exchange furnace body, a chimney is installed at the top of the heat exchange furnace body, and a hot water cavity is arranged in the position, outside the heat exchange furnace body, of the heat preservation furnace body. Adding of the biomass fuel is facilitated, sufficient burning of the biomass fuel is guaranteed, heat in the burning hearth is conveniently transmitted into the hot water cavity to heat water in the hot water cavity, the falling speed of the biomass fuel is decreased through the heat exchange stopping rod, and sufficient burning of the biomass fuel is guaranteed; and by means of the heat exchange stopping rod, the contact area between the biomass fuel and flames is increased, and therefore inside waste communicated with the hot water cavity can be conveniently heated.

Description

technical field [0001] The invention relates to the technical field of energy-saving equipment, in particular to a three-dimensional biomass fuel energy-saving boiler. Background technique [0002] Small boilers are widely used in the market. Schools, hospitals, township clothing, non-staple food and other processing enterprises far away from main cities and remote areas need small boilers for heating. The vast rural breeding industry needs heat energy. Renewable biomass energy, such as orange stalks, rice bran, etc., can be used in small-scale low-pressure domestic boilers. [0003] At present, most small-capacity domestic boilers adopt the structure of vertical fire tube boilers or improved vertical horizontal water tube boilers, which have the advantages of simple structure and small footprint, but generally suffer from insufficient output, low operating thermal efficiency, Fatal shortcomings such as high exhaust gas temperature, among them, when the vertical fire tube b...

Problems solved by technology

[0003] At present, most small-capacity domestic boilers adopt the structure of vertical fire tube boilers or improved vertical horizontal water tube boilers, which have the advantages of simple structure and small footprint, but generally suffer from insufficient output, low operating thermal efficiency, Fatal shortcomings such as high exhaust gas temperature, among them, when the vertical fire tube boiler is burning, the biomass fuel is easy to pile up after being put in, or it is discharged from the slag discharge port due to insufficient combustion due to too fast falling speed, and the energy saving effect is poor , does not meet the national requirements for energy conservation and emission reduction

Secondly, due to the limitation of the furnace structure, the heating area of ​​the furnace wall is limited, and the thermal efficiency is relatively low, which cannot meet the requirements of energy saving and cost reduction
