Abstract

An energy-saving and multipurpose stove solves many problems of prior small-sized stoves using gas, oil, molded coal and electric energy. The problems comprises that flue gas is discharged directly, the bulk is great, the area of a wall-cooling surface is big, fuel can not be burned sufficiently, heat efficiency is low, and harmful gas and smoke are discharged too much. A heat exchange assembly arranged in a furnace mantle comprises a framework formed by solid materials and a heat-gathering tank formed by tight fit of water jackets, some small hearths arranged on a wall of the heat-gathering tank lead a room for continuous burning to communicate with an internal furnace. The utility model has the advantages of compact structure, small bulk of the stove, long length of life, sufficient burning, fast elevation of temperature and remarkable drop of the formation and discharge amount of nitrogen oxides in the stove.

Description

The energy-saving multi-purpose stove

The utility model is a kind of energy-saving multi-purpose stove.

Small-sized stoves such as existing combustion gas, fuel oil, moulded coal, electric energy, its structure is fire-tube type, waterpipe type, water-jacket typ basically, it is in line that flue gas is; Volume is big, and water capacity is many, and the water-cooling wall area is big, and fuel combustion is insufficient, and heat flow density is little in the burner hearth that has, and it is insufficient to exist the interior available energy of stove to utilize, and heat is imitated low, the energy consumption height, and pernicious gas and soot emissions are many, use unsafe problems.

The purpose of this utility model is, solves existing existing problem, and a kind of have environmental protection, efficient, energy-saving multi-purpose stove are provided.

The utility model is achieved in that the heat exchange assembly is set in furnace shell, and the heat exchange assembly comprises the heat gathering tube that skeleton that solid material constitutes and water jacket closely cooperate and constitute, and inner chamber is big burner hearth; The heat build-up barrel is provided with several little burner hearths, and the afterflame chamber is communicated with internal furnace; At heat gathering tube and furnace shell top movable bell is set, is provided with outlet flue and secondary air mouth on the furnace shell wall, water jacket is provided with water inlet, delivery port and draws outside the body of heater.

Advantage of the present utility model is, 1, the heat exchange assembly comprises the heat gathering tube that skeleton that solid material constitutes and water jacket closely cooperate and constitute, and inner chamber is big burner hearth; The heat build-up barrel is provided with several little burner hearths, and the afterflame chamber is communicated with internal furnace; Make its compact conformation, furnace volume is little, long service life.2, no visible water-cooling wall in the furnace shell, the fuel combustion environment is good, sufficient combustion, the heating surface area that the radiation of high-temperature flue gas, grit and convection current are washed away is big; The flue dust that is detained in the stove is many, and it is few to discharge out of the furnace, and the available energy utilization is abundant.Aggregate blackness in the heat gathering tube is big, and thermal conductivity is good, and the density of skeleton is big, and heat build-up is many, and the heat flow density of passing to water jacket is big, and water jacket wall is led warm good, and current are long at the hot environment stroke, quick heating, and flow dynamic is big, and stove is safe in utilization.3, reducing under the chamber temperature situation, the operation of stove is normal, and stove internal combustion mode is the stage burning method, and this has just reduced the generation and the discharge capacity of nitrogen oxide in the stove significantly.
