Abstract

The utility model discloses a biomass power economized boiler which comprises a boiler body, wherein a fire grate is arranged on the bottom of the boiler body, a boiler arch is arranged in the middle of the boiler body, a combustion chamber is arranged between the fire grate and the boiler arch, a combustion ash chamber is arranged above the boiler arch, a smoke chamber is arranged above the combustion ash chamber, a feeding device and a secondary air duct which are communicated with the combustion chamber are arranged on the lateral wall of the boiler body, a primary air duct is formed in the fire grate, explosion doors are arranged on a smoke outlet of the smoke chamber and at the top end of the combustion ash chamber, and a plurality of sets of special-shaped flues communicated with the combustion ash chamber and the smoke chamber are formed in the boiler arch. The biomass power economized boiler has the advantages that due to the arrangement of the primary air duct and the secondary air duct, the using rate of fuel is improved; due to the fact that the explosion doors are additionally arranged on the smoke outlet of the smoke chamber and at the top end of the combustion ash chamber, the safety coefficient of operation of the boiler is increased; the structure is simple; user friendliness is achieved.

Description

A kind of energy-saving biomass boiler

Technical field

The utility model relates to a kind of energy-saving biomass boiler, belongs to the boiler technology field.

Background technology

Biomass boiler is as fuel with biomass energy, be divided into biomass steam boiler, biomass hot water boiler, the biomass thermal wind furnace, the biomass heat-conduction oil oven, the vertical type biomass boiler, horizontal biomass boiler etc., the bio-fuel strong adaptability of its main use, such as four seasons agricultural crop straw, forestry waste, but these biomass fuel water content are larger, can reach 10-20%, existing boiler combustion is insufficient, the utilization rate of fuel is lower, the exhaust gas volumn of these fuel is larger simultaneously, potential safety hazard easily appears, the safety coefficient of boiler operatiopn is lower.

Summary of the invention

The purpose of this utility model is to provide a kind of energy-saving biomass boiler, can improve the utilization rate of fuel, increases the safety coefficient of boiler operatiopn.

The purpose of this utility model is achieved through the following technical solutions: a kind of energy-saving biomass boiler, comprise body of heater, the bottom of body of heater is provided with fire grate, the middle part of body of heater is provided with chimney arch, be provided with combustion chamber between fire grate and chimney arch, the chimney arch top is provided with burning chamber, the burning chamber top is provided with smoke chamber, be provided with the feeder and the secondary air duct that are communicated with combustion chamber on the sidewall of described body of heater, be provided with air channel on fire grate one time, the exhaust opening of described smoke chamber and the top of burning chamber are provided with explosion proof door, be provided with the special-shaped flue that many groups are communicated with burning chamber and smoke chamber on chimney arch.

The bottom of described burning chamber is provided with cleaning door.

Described special-shaped flue is upper and lower staggered floor and distributes.

The beneficial effects of the utility model are: be provided with air channel and secondary air duct, improve fuel utilization rate, set up explosion proof door at the exhaust opening of smoke chamber and the top of burning chamber, increased the safety coefficient of boiler operatiopn, and there are characteristics simple in structure, easy to use simultaneously.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is schematic cross-section of the present utility model;

Fig. 3 is principle schematic of the present utility model.

Wherein, 1-body of heater, 2-fire grate, 3-chimney arch, 4-combustion chamber, 5-burning chamber, 6-smoke chamber, 7-feeder, air channel of 8-, 9-secondary air duct, 10-explosion proof door, 11-abnormity flue, 12-cleaning door.

The specific embodiment

Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.

As Fig. 1, Fig. 2, a kind of energy-saving biomass boiler, comprise body of heater 1, the bottom of body of heater 1 is provided with fire grate 2, the middle part of body of heater 1 is provided with chimney arch 3, be provided with combustion chamber 4 between fire grate 2 and chimney arch 3, chimney arch 3 tops are provided with burning chamber 5, burning chamber 5 tops are provided with smoke chamber 6, be provided with the feeder 7 and the secondary air duct 9 that are communicated with combustion chamber 4 on the sidewall of described body of heater 1, be provided with air channel 8 on fire grate 2 one time, the top of the exhaust opening of described smoke chamber 6 and burning chamber 5 is provided with explosion proof door 10, increased the boiler operatiopn safety coefficient, be provided with the special-shaped flue 11 that many groups are communicated with burning chamber 5 and smoke chamber 6 on chimney arch 3.

The bottom of described burning chamber 5 is provided with cleaning door 12, can prevent long-term knot ash, causes slagging scorification to be stain, and makes heating surface lower heat-transfer effect.

Described special-shaped flue 11 is upper and lower staggered floor and distributes, and has reached the effect of secondary ash disposal.

As Fig. 3, fuel enters combustion chamber 4 by feeder 7, the air-flow that while air channel 8 and secondary air duct 9 and feeder 7 are brought into, form the air-supply of convection type angle, carry out the cyclone type burning with fuel, improved energetically the biomass fuel combustion effect, full combustion of fuel, burner hearth is heated evenly, the burner hearth area is large simultaneously, the length of flame lengthens, having strengthened radiation is heated, the thermal efficiency is improved, reduced the heating surface coefficient of friction, increased pot stove service life, as shown by arrows, flue gas enters burning chamber 5 and enters into smoke chamber 6 by special-shaped flue 11 and finally discharges out of the furnace.
