Abstract
The utility model discloses a biomass fuel boiler, which has a split-type structure. The biomass fuel boiler consists of an upper furnace body and a lower combustion base, wherein the combustion base comprises a combustion base body; a fire grate is arranged in the combustion base body and partitions the combustion base body into an upper combustion chamber and a lower combustion chamber; a fire door is arranged on the upper combustion chamber, and a plurality of secondary air inlets are uniformly formed on the upper combustion chamber; and a slag cleaning port is formed on the lower combustion chamber, and a plurality of primary air inlets are uniformly formed on the lower combustion chamber. The biomass fuel boiler with the split-type structure has a simple structure and is economic, convenient and practical; materials are manually fed into the fire door; compared with the conventional automatic material feeding mode, the manual material feeding mode has the advantages that large biomass materials such as mushroom slag and saw dust can be put into the boiler without being crushed into small pieces so as to be used conveniently; the materials can be combusted only under the heat of about 3,000 kilocalories instead of 3,600 kilocalories, so that the heat efficiency of the materials is higher than that of coals.
Description
Technical field
The utility model relates to a kind of biomass fuel boiler.
Background technology
Biomass boiler probably is divided into two types by its purposes at present: a kind of is living beings heat energy boiler, and another kind is a living beings electric energy boiler.
In fact, the principle of the two is basic identical, all is to obtain energy through firing biomass fuel, and just first kind is directly obtained heat energy, and second kind changes into electric energy again with heat energy.In these two kinds of boilers, first kind is again that application is the most extensive now, technological comparative maturity.
If continue segmentation, first kind of boiler---living beings heat energy boiler can also be divided three classes:
The first kind: small-sized biomass heat energy boiler.This kind boiler uses the biomass fuel that solidifies or gasify, and the heat energy of hot water form is provided, and its advantage is that volume is little, and simple in structure, price is low; Shortcoming is, energy loss is big, and Fuel Consumption is big, and the heat energy quantity delivered is low, can't satisfy the big user of heat energy demand, and this kind boiler target is the heating of single household rural households and domestic hot-water's supply.
Second type: medium-sized living beings heat energy boiler.This type of boiler mainly uses solidified biological matter fuel, and hot water or steam are provided.Its advantage is technological comparative maturity, and energy loss is little, and the heat energy supply capacity is stronger; Shortcoming is the coking of part boiler oil, and supporting design is unreasonable.At present " the spiral wind wing Burner Technology " of Shandong Xi Er biomass energy company well solved phenomenons such as the burning of medium-sized biomass boiler is insufficient, coking.
The 3rd type: macro-organism matter heat energy boiler.This type of boiler does not have actual product at present, and main cause is existing technology and imperfection, and it is unsound to substitute coal-fired national policy for living beings, therefore, only rests on conceptive.What it was stressed is a kind of centralized management, central controlled Thermal Power Engineering, and boiler guarantees the normal operation of whole living beings heat energy engineering only as one of them equipment, and therefore, it requires very high to fuel, combustion technology, supporting technology, relevant policies.
Prior biological matter fuel boiler operated by rotary motion has special feeding system, is made up of parts such as feed bin, vibra feeder, screw(-type) feeder, screw feeder pipes like feeding system, after so just requiring raw material pulverized; Could be the boiler transferring raw material well, one side needs to consume a large amount of electric energy, uses also very inconvenient on the other hand; And owing to receive the restriction of its structure, air inlet system need could be realized circulation by blower fan; This also need consume a large amount of electric energy; And the structure of air inlet system is unfavorable for that biomass fuel fully burns, and boiler thermal output is lower.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, and a kind of biomass fuel boiler is provided, and it adopts split-type structural; Simple in structure, economical, convenient, practical, carry out manual charging from fire door; Contrast automatic feed in the past, can put into the biological material of bulk, need the bulk biological material be ground into fritter; Make the biological material of bulk, can be able to easily use like bacterium slag and wood chip, and higher than the thermal efficiency of coal.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of biomass fuel boiler; Said boiler is a split-type structural; Constitute by top body of heater and bottom burning base; Said burning base comprises burning base body, is provided with fire grate in the said burning base body, and the said fire grate base body that will burn is divided into combustion chamber, top and lower combustion chamber; The combustion chamber, top is provided with a fire door, and evenly is provided with a plurality of secondary air mouths; Lower combustion chamber is provided with a breast hole, and evenly is provided with a plurality of air inlets.
Said fire door and breast hole are provided with removable lid.
Said secondary air mouth and an air inlet are provided with volume damper.
The utility model is simple in structure, and is economical, convenient, practical, adopts split-type structural, and bottom burning base can use a lot of on the market, that price is also more relatively cheap Micropressure boiler and normal-pressure boiler to replace dual purpose steam water boiler, material benefit more economically.
The utility model carries out manual charging from fire door, contrasts automatic feed in the past, can put into the biological material of bulk; Need the bulk biological material be ground into fritter, make the biological material of bulk, can be able to easily use like bacterium slag and wood chip; Now only need the bacterium bits of bulk to add the overwood slag; Be pressed into just can burning of bulk then, manual charging no longer need be pressed into the charging of granule; And want could burn about 3600 kilocalories in the past, just can fully burn about present 3000 kilocalories, the more economical material benefit of the biomass fuel of this bulk.And it is higher than the thermal efficiency of coal.
The air intake and the secondary air of the utility model all are natural air inlets, do not re-use blower fan, reduce cost greatly.
The utility model fire door, remove slag the door and air inlet be provided with closable lid.The convenient burning condition of regulating guarantees efficiency of combustion.
