Abstract
The invention firstly provides a combustion air supply system in a biomass combustion furnace. The combustion air supply system comprises a small fan, an air blower and an air distribution tank which are sequentially connected in series, wherein the small fan is a fan which is powered by a battery and has the power of 10 to 200 w; the air blower is a fan which has fan power higher than the power of the small fan and is used for providing main fresh air for the combustion furnace; the air distribution tank is used for distributing fresh air and comprises a plurality of outlets which are connected in parallel; and the plurality of outlets which are connected in parallel are respectively connected with a main blast pipe, a discharge pipe anti-backfire blast pipe and blast pipes for other purposes. The combustion air supply system provides a safe and efficient working environment for the biomass combustion furnace. The invention further correspondingly provides a combustion furnace and a heating device.
Description
Technical field
The present invention relates to technical field of combustion equipment, the burning air supply system that is specifically related in a kind of biomass combustion furnace, burning
Stove and heating equipment.
Background technology
In since cured tobacco production and popularization more than 100 year, the history in coal baking tobacco leaves existing more than 50 years, coal toasts
Replace original firewood to toast, be the much progress in tobacco roasting history, weigh for protecting forest resources to have made with ecological environment
Contribute.In recent years, tobacco business absorbs Foreign Experience and technology, and bulk curing barn success is promoted in exploitation, bakes from tradition
Room, to bulk curing barn, is the another much progress in tobacco roasting history, significantly improves the utilization rate of the energy, effectively reduce baking
It is roasted into this.But, bulk curing barn the most fundamentally solves the present situation toasted with coal for the energy, coal constantly consume with
And the local pollution of the environment problem that barn clustered is brought the most increasingly displays.Coal toasts dust, the carbon discharged

The real-time heating load of individual heating equipment so that the dry-bulb temperature in barn and wet bulb temperature and heating-up time, surely temperature time etc.
The equal controllable precise of parameter.Wherein without the variations in temperature of instability fluctuated, do not result in cold dust and hot dust etc. without using
The low quality Nicotiana tabacum L. being worth, the quality of tobacco baked is good.It addition, the tobacco flue-curing program that automatization's standard is arranged can be kept away
Exempt from a lot of maloperation and bring waste product, and make the quality of Nicotiana tabacum L. the most well-balanced more preferably.
4, saving of work and time: full-automatic setting can save substantial amounts of manual labor.Whole process the most only needs manpower by biomass
Granular fuel send into concentrate feeding system storage vat in (this process also can complete by machinery), and the slag of after-flame from
The breast hole of heat exchanger clears.Feeding system is concentrated automatically from storage vat 32, biological particles to be sent into vacuum
In hopper 37, automatically sending into hopper 11 by biological particles from vacuum hopper 37 after feed, burning air supply system is certainly
The air capacity in combustion furnace is sent in dynamic regulation, and the slag in burner hearth and the most not sufficiently combusted clout are pushed away by slag removal mechanism automatically
Enter and heat exchanger carry out second-time burning, in burner hearth burning and heat exchanger in second-time burning produce high-temperature flue gas after dedusting
Discharging from chimney after at radiator heating the circulation air in barn, the high low speed circulating fan 46 in barn promotes barn
Interior hot-air circulates and from flowing into for hot cell 41 to hang, Nicotiana tabacum L. carries out smoke-box 42 heated baking, hangs the temperature in smoke-box
Degree and humidity are also adopted by automatically controlling equally.These processes are carried out the most automatically, save substantial amounts of manpower and time.And keep away
Exempting from people to contact with the direct of burning fuel, beneficially tobacco grower's is healthy.
5, efficient energy-saving: the present invention changes in first technology the mode of suspension combustion in combustor b, changes biological particles into
Controllably it is deposited in converter nose burning, then by adjusting the burning air supply system of the present invention so that its efficiency of combustion is entered by 82%
One step brings up to 87%, and the raising of efficiency of combustion produces remarkable result to energy saving of system.It addition, the present invention is good at exhaust emissions
Get well and in the case of combustion furnace noncoking, not slagging scorification, be not required to provide the strong impetus so that biological particles suspension combustion and energy
Amount consumes, and reduce further the energy consumption of whole combustion furnace and heating equipment.
6, the service life of equipment is long: this heating equipment uses the steel of special substance, has high temperature resistant, anticorrosion, prolongs
The features such as long life；Equipment surface application and through blasting treatment make surface cleanness grade reach GB/T 8923 regulation
Sa2.5 level requirement, surfaces externally and internally uses high temperature, epoxy zinc rich primer to carry out three road sprayings, and finish paint uses electrostatic spraying (roasting
Paint), the feature that this technique has high temperature resistant, resistant to strong corrosion, increases the service life, the life-span of this heating equipment typically may be used
Reach more than 12 years, more durable in use than other heating equipment.
7, equipment is applied widely: this heating equipment can be accomplished to dock easily and combine closely with all kinds of barns, and this confession
Hot equipment is suitable for mobile, as cigarette can be planted but this year can not plant former years by some cigarette district, must change to another place kind, the most permissible
A whole set of biomass granule fuel heating equipment is moved to other flue-cured tobacco district toast.Additionally, the heat supply that the present invention provides sets
The standby drying plant being also used as various agricultural product, including medical material, Oryza glutinosa, Flos Lonicerae, Radix hemerocalis plicatae etc..
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For Yuan, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made,
Equivalent, improvement etc., should be included within the scope of the present invention.
