Description

Single drum longitudinal biomass direct-fired chain-grate boiler system
Technical field
The present invention relates to boiler structure field, be specially single drum longitudinal biomass direct-fired chain-grate boiler system.
Background technology
Along with the development of society, coal and oil equal energy source are the most exhausted, and society is to ecological environment pay attention to day by day, society simultaneously Can be more and more higher to the degree of concern of renewable and clean energy resource.Biomass as a kind of recyclable fuel have few sulfur or without sulfur, The feature that high volatile easy firing, ash are few, moisture changes greatly, carbon dioxide can fully absorb in life cycle, because This, the flue gas after biomass combustion is typically without installing desulphurization plant, and under same combustion system, the original dust emissions of boiler is dense Spend lower than coal, and combustion zone temperature be more much lower than coal, can reduce thermal NO x generate, therefore biomass fuel in recent years by Gradually being used widely, particularly biomass fuel is when mediumand smallscale industrial boilers, has preferable economy.But it is biological Matter fuel there is also the clean-burning problem that is difficult to catch fire owing to moisture content is high, thus affects its application.
Summary of the invention
For the problems referred to above, the invention provides single drum longitudinal biomass direct-fired chain-grate boiler system, it can solve It is difficult to clean-burning problem of catching fire owing to biomass fuel moisture content is high.
Its technical scheme is, single drum longitudinal biomass direct-fired chain-grate boiler system, and it includes biological hopper and boiler Body, is provided with combustor in described boiler body, described combustor inner bottom part arranges traveling-grate stoker, and described biological hopper is arranged at Outside described boiler body and be positioned at chain fire-gate feed inlet end, described top of combustion chamber exhanst gas outlet is connected successively by flue It is connected to air preheater, economizer, cleaner unit and chimney, it is characterised in that: it also includes external dehydrator, and described external dehydrator leads to Crossing Material pipeline road to be connected with described biological hopper, described air preheater is connected by smoke pipe with described external dehydrator.
Further, described air preheater includes interconnective first air preheater and the second air preheater, described burning ceiling Portion's exhanst gas outlet is connected with described first air preheater by flue, and described first air preheater and described external dehydrator pass through smoke pipe Connecting, described second air preheater is connected with described economizer.
Further, described boiler body uses pan shell type threaded flue structure.
Further, being provided with secondary air-jet device at the face arch of described boiler body, described secondary air-jet device uses and becomes Frequently overfire air fan.
Further, described boiler body top nose arranges front smoke box and checks hole.
The beneficial effects of the present invention is: it is incorporated into external dehydrator by air preheater changes thermogenetic high temperature air The biomass fuel of high-moisture percentage is carried out heating, drying to reduce fuel moisture, then the biomass fuel conveying after drying The most biological hopper is interior and is delivered to fully burn on the traveling-grate stoker in boiler body, thus reaches high-moisture percentage biomass fuel The purpose that material the most effectively utilizes.

Detailed description of the invention
Seeing Fig. 1, Fig. 2 and Fig. 3, single drum longitudinal biomass direct-fired chain-grate boiler system, it includes biological hopper 1 and pot Furnace body 2, is provided with combustor in boiler body 2, combustor inner bottom part arranges traveling-grate stoker 3, and biological hopper 1 is arranged at boiler originally Outside body 2 and be positioned at the feed inlet end of traveling-grate stoker 3, it is empty that top of combustion chamber exhanst gas outlet 4 is connected with first in turn by flue Pre-device the 5, second air preheater 6, economizer 7, cleaner unit 8 and chimney 9;It also includes that external dehydrator 10, external dehydrator 10 lead to Crossing Material pipeline road 11 to be connected with biological hopper 1, the first air preheater 5 is connected by flue 12 with external dehydrator 10;Boiler Body 2 uses pan shell type threaded flue structure, thus controls flue gas flow rate below 12 meter per seconds, prevents smoke pipe from wearing and tearing;Boiler is originally Being provided with secondary air-jet device 13 at the face arch of body 2, secondary air-jet device 13 uses frequency conversion overfire air fan, it is possible to effectively control secondary Wind wind speed, strengthens the disturbance of high temperature, increases the flue gas time of staying in stove, makes burning more fully to improve efficiency of combustion; Boiler body 2 top nose arranges front smoke box and checks hole 14, in order to the fashionable deashing of energy, prevents blocking.
Single drum longitudinal biomass direct-fired chain-grate boiler system of the present invention, biomass fuel is defeated by biomass hopper 1 Entering, burn on traveling-grate stoker 3, the first sky that high-temperature flue gas sequentially enters afterbody after boiler body radiation and convection current heat absorption is pre- Device the 5, second air preheater 6, economizer 7, after water dust scrubber 8 dedusting, drawn by air-introduced machine and enter air into chimney;Work as biology When the moisture content of matter fuel is higher, the high temperature air drawn by the first air preheater 5 introduces external dehydrator 10, to high-moisture percentage Biomass fuel carries out high temperature drying, and the biomass fuel after drying is transported to biological material 1 by Material pipeline 11, enters back into Burning in boiler body 1.
