Abstract

The utility model discloses a hot blast heating boiler with biomass briquette fuel, which comprises a boiler body, a hearth, a grate, an air inlet of the lower part of the grate, a filling port of the upper part of the grate, a smoke passage on the upper part of the hearth, and a chimney on the smoke passage, wherein an annular air passage is arranged between the hearth and a boiler wall; the annular air passage is communicated with the smoke passage on the upper part of the hearth. A cold air inlet communicated with the annular air passage is arranged on the boiler wall; the cold air inlet is communicated with an outlet of a blower; a tube array heat exchanger is arranged in the smoke passage. A hot air outlet pipeline is communicated with an open type radiator which is composed of a transverse air inlet tube and a longitudinal tube array; an upper port of each tube of the longitudinal tube array is communicated with an air outlet on the transverse air inlet tube and a lower port is open. The burning performance of the heating boiler is good; the heating efficiency is high. NOx, CO, SO2, etc. in smoke discharged by the boiler are below the environmental protection index; the utility model has better energy saving and environmental protection efficiencies. The manufacturing process of the hot blast boiler is easy; the operation is convenient.

Description

The biomass molding fuel hot-blast stove

Technical field

The utility model relates to a kind of heating stove, especially a kind of biomass fuel hot-blast stove.

Background technology

Existing heating stove all is to act as a fuel with coal or bavin, and as heat transfer medium, the principle of carrying out heat exchange by radiator realizes heating with water.The energy consumption height pollutes greatly, and heating efficient is undesirable.

The utility model content

The purpose of this utility model provides a kind of novel structure, and fuel combustion is complete, thermal efficiency height, and smoke evacuation reaches the biomass fuel hot-blast stove of environmental requirement.

The technical solution of the utility model is: a kind of biomass molding fuel hot-blast stove, comprise the air inlet of body of heater, burner hearth, fire grate, fire grate bottom, feeding port and the exhaust gases passes of upper furnace and the chimney on the exhaust gases passes on fire grate top, between burner hearth and furnace wall, be provided with annular air channel, the exhaust gases passes UNICOM of this annular air channel and upper furnace; Be provided with the cold wind import with annular air channel UNICOM on the furnace wall, cold wind import and blower export UNICOM are provided with tubular heat exchanger in exhaust gases passes; Hot air outlet pipeline and open radiator UNICOM, open radiator by horizontal air inlet pipe and vertically tubulation forms, the vertical gas outlet UNICOM on the upper port of each pipe of tubulation and the horizontal air inlet pipe, lower port is open.

In annular air channel, be provided with the screw type fin.

Advantage of the present utility model:

This stove is to adopt air heating rather than heat room air with media water, the biomass molding fuel hot-blast stove mainly is made up of burner hearth, fire grate, radiation and heat convection face, chimney, radiator, inlet of cold air, hot air outlet, feeding port, two ash holes etc., this heating stove combustibility is good, the heat supply efficiency height; NO in the smoke evacuation of stove x, CO, SO2 etc. are lower than environmental protection index, and energy-conservation preferably and environmental benefit are arranged; This hot-blast stove manufacturing process is simple, processing ease.

Description of drawings

Fig. 1 is the utility model structural representation,

Fig. 2 is open heat spreader structures schematic diagram.

The specific embodiment

The utility model structure is as depicted in figs. 1 and 2: comprise the air inlet 1 of body of heater 17, burner hearth 5, heat-insulation layer 4, fire grate 2, fire grate bottom, feeding port 16 and the exhaust gases passes 8 of upper furnace and the chimney 11 on the exhaust gases passes on fire grate top, between burner hearth and furnace wall, be provided with annular air channel 3, exhaust gases passes 8 UNICOMs of this annular air channel and upper furnace are provided with screw type fin 6 in annular air channel; Be provided with the cold wind import 13 with annular air channel UNICOM on the furnace wall, the outlet UNICOM of cold wind import 13 and air blast 14 is provided with tubular heat exchanger 10 in exhaust gases passes; Hot-air channel is by pipeline and open radiator 12 UNICOMs, and open radiator is made up of horizontal air inlet pipe 18 and vertical tubulation 19, the gas outlet UNICOM on the upper port of vertical tubulation 19 each pipe and the horizontal air inlet pipe 18, and lower port is open gas outlet 20.

The hot-blast stove operation principle:

Fuel is after lighting a fire successfully on the fire grate 2, and forming blocks enters the burner hearth 5 of red-hot bed material from charging aperture 16, and according to the easily ignitable combustion characteristics of living beings, will blaze up a moment.Air blast 14 at cold wind mouth 13 places blasts indoor cold air in the burner hearth interlayer 3, the fin 6 that is with outward around burner hearth is arranged in the burner hearth interlayer 3, air all around flows while being heated guided upwards by fin at burner hearth, prevent that so promptly air from producing short circuit in interlayer, make air in interlayer, stop more time again.Heated air passes burner hearth interlayer 3, enter upper furnace tubulation radiator 10 places, wash away the tubulation radiator and flowing to hot air outlet 7, enter in the interior open radiator 12 of hot air duct and inlet chamber, hot-air 15 is distributed to the room from each little cavity of open radiator bottom, and this moment, temperature and speed all had substantial degradation.The high-temperature flue gas trend is: come out directly to enter in the upper furnace tubulation radiator 8 from burner hearth 5, heat the air of circumferential flux warp, enter chimney 11 rows afterwards to the external world.

Claims (2)

1, a kind of biomass molding fuel hot-blast stove, comprise the air inlet of body of heater, burner hearth, fire grate, fire grate bottom, feeding port and the exhaust gases passes of upper furnace and the chimney on the exhaust gases passes on fire grate top, it is characterized in that: between burner hearth and furnace wall, be provided with annular air channel, the exhaust gases passes UNICOM of this annular air channel and upper furnace; Be provided with the cold wind import with annular air channel UNICOM on the furnace wall, cold wind import and blower export UNICOM are provided with tubular heat exchanger in exhaust gases passes; Hot air outlet pipeline and open radiator UNICOM, open radiator by horizontal air inlet pipe and vertically tubulation forms, the vertical gas outlet UNICOM on the upper port of each pipe of tubulation and the horizontal air inlet pipe, lower port is open.
2, biomass molding fuel hot-blast stove according to claim 1 is characterized in that: be provided with the screw type fin in annular air channel.
