Abstract

A water heater with improved furnace body in structure features use of 4 techniques including promoting combustion with vapour, secondary wind supply, sucking heat by circulating flow and afterheat utilization. Its advantages include saving energy, high efficiency and thermal utilization rate, increased the combustible rate of fuel and less environmental pollution.

Description

The hot-water heating stove

What the present invention relates to is a kind of efficient energy-saving hot-water heating stove.

The hot-water heating stove that existing market is sold, basic structure and traditional not very big difference of warming furnace, just body of heater is become big, inside has installed the heat absorption water jacket additional or added the V-type wing again on water jacket, to improve heat exchange effect, defective such as the combustibility that seriously exists coal is poor, the heat energy utilization rate is low, environmental pollution is bigger.

The energy-efficient hot-water heating stove of defectives such as for addressing the above problem, we have reformed furnace binding on the basis of practice, and it is poor to design a kind of combustibility that can fundamentally overcome coal, and the heat energy utilization rate is low, environmental pollution is big.

Purpose of the present invention is primarily characterized in that: the employing steam is combustion-supporting, secondary is given wind, circulation absorbs heat, the UTILIZATION OF VESIDUAL HEAT IN means, and the hot-water heating stove heat effect of its innovation and creation has been reached more than 85%.

The objective of the invention is to adopt following measures to realize:

Accompanying drawing is the structural representation of hot-water heating stove, and it mainly is made of the following part of organizing separately: stone or metal plate for standing a stove on as a precaution against fire 1, coal filling hole 2, insulation material 3, annular heat absorption water jacket 4, water jacket 5, secondary wind inleting tube 6, shell 7, connect ash bucket 8, furnace bottom 9, induced duct 10, movable fire bars 11, grate 12, grate supports 13, water return outlet 14, steam jeting tube 15, secondary is to wind dish 16, connecting leg 17, steam pipe 18, flue dust is removed mouth 19, waste heat absorption tube 20, supply water and export 21, chimney interface 22, firepower control panel 23, steam generator 24, endothermic tube 25, stove circle 26, bell 27 product that is assembled.

Be design feature and the principle that clearly reaches purpose of design, existing combustion-supporting to steam respectively in conjunction with schematic diagram, secondary is described below for the project organization know-why of wind, circulation heat absorption, UTILIZATION OF VESIDUAL HEAT IN and subsidy measure:

Steam is combustion-supporting---steam jeting tube 15 is housed, constantly to the furnace injection steam, because the H in the steam below grate 12 ₂O quickens the cracking of fuel, and has further participated in burning, has improved the combustibility of burning, makes fuel combustion more complete, has improved the hearth box temperature.

Secondary is given wind---locate to be provided with secondary to wind dish 16 at coal filling hole 2 (fire door); it be connected from 12 times induced ducts 10 of grate; supply with the flame that also has denseer coal gas at fire door through the fresh air that gives heat; impel the coal gas burning again in the flame; make almost all burnings of effective ingredient of coal; both save the energy, also protected environment simultaneously.

Circulation heat absorption---coal filling hole has installed horseshoe-shaped circulation heat absorption water jacket 4 additional more than 2, make the fire temperature enter the ring-type road from the place ahead breach, flame is in this glide path that extended, under the situation of annular heat absorption water jacket 4 and water jacket 5 abundant absorption heat energy, enter chimney again, thereby reach the purpose that makes full use of heat energy.

UTILIZATION OF VESIDUAL HEAT IN---because of entering the flue gas of chimney, temperature is also very high, and this part waste heat still has value, and three endothermic tubes 25 are housed in chimney, and steam generator 24 also is equipped with in the front portion, and waste heat is fully used.

Ancillary method has: for the ease of deashing, movable fire bars has been installed on grate 12, only need have been shaken movable fire bars handle during deashing and get final product; For indoor clean hygiene, loaded onto and connect ash bucket 8, prevent that dust from rippling; Coal filling hole 2 has been offered on top, has removed the indoor pollution that brings at bell top coal; Stove circle 26 is cast spill down, and the speed of cooking is improved near flame in the bottom of a pan when cooking; Chimney bottom has been offered flue dust and has been removed mouth 19, is convenient to make regular check on the removing flue dust, keeps chimney unimpeded; Firepower control panel 23 is equipped with in chimney top, can warm oneself, cook and the needs that bank up a fire night, the free adjustment gap according to own.

By adopting above four technological means and ancillary method that the flammable rate of fuel and heat energy utilization rate are improved greatly, the thermal efficiency can reach more than 85%, has saved the energy; Reduce the chimney pollution simultaneously, protected environment.

Claims

1, adopted that steam is combustion-supporting, secondary is given wind, circulation heat absorption, four technological means of UTILIZATION OF VESIDUAL HEAT IN, the flammable rate and the heat energy utilization rate that have reached fuel improve greatly, hot effect can reach more than 85%, has saved the energy, has reduced the chimney pollution, has protected environment.

2, according to the function know-why of claim 1, it is characterized in that: when adopting the steam combustion supporting technology, steam jeting tube 15 is housed below grate 12, constantly to the furnace injection steam, because the H in the steam ₂O quickens the cracking of fuel, and has further participated in burning, has improved the combustibility of burning, makes fuel combustion more complete, has improved the hearth box temperature.

3, according to the function know-why of claim 1; its feature also is: when adopting secondary to give the wind technology; be provided with secondary to wind dish 16 at the fire door place; it be connected from 12 times induced ducts 10 of grate; supply with the flame that also has denseer coal gas through the fresh air that gives heat at fire door, impel the coal gas burning again in the flame, make almost all burnings of effective ingredient of coal; both save the energy, also protected environment simultaneously.

4, according to the function know-why of claim 1, its feature also is: when adopting circulation heat absorption technology, install horseshoe-shaped circulation heat absorption water jacket 4 more than the fire door additional, make the fire temperature enter the ring-type road from the place ahead breach, flame is in this glide path that extended, under the situation of annular heat absorption water jacket 4 and water jacket 5 abundant absorption heat energy, enter chimney again, thereby reach the purpose that makes full use of heat energy.

5, according to the function know-why of claim 1, its feature also is: when adopting the UTILIZATION OF VESIDUAL HEAT IN technology, because of entering the flue gas of chimney, this part waste heat still has value, three endothermic tubes 25 are housed in chimney, and steam generator 24 also is equipped with in the front portion, and waste heat is fully used.
