Description
The present invention relates to a kind of simulation fireplace of use biomass fuel, use the little particle suppressed by the crushing such as straw, wood chip, agricultural crop straw as fuel and the heating simulation fireplace with high heat exchanger effectiveness more particularly in a kind of.
Biomass fuel is the little particle that compacting is crushed by straw, wood chip, agricultural crop straw etc..Biomass fuel is as a kind of new energy because its health, environmental protection, efficient, economic dispatch advantage have begun to gradually be widely applied.
Simulation fireplace is a kind of common equipment, can be only used as decoration and use, it is possible to have heating function.Simulation fireplace with heating function is typically originated using electric energy as energy, but electricity consumption is originated with costly as energy, heats the major defect such as slow.If using biomass fuel pellet as the energy, the topmost technical problem faced is how in traditional simulation fireplace this limited volume sufficiently to complete heat exchange, and the gas temperature of outdoor is discharged after reduction burning, energy dissipation phenomenon is reduced.Because in the conventional technology, heat exchange is mainly what is completed by flue gas smokejack, if requiring heat exchange fully, the EGT of discharge is low, can only just increase the length of smokejack, thus inevitably to increase the volume of fireplace.
The technical problems to be solved by the invention are to provide a kind of simulation fireplace of use biomass fuel, and the simulation fireplace had not only had the volume of very little but also with higher capacity usage ratio.
In order to solve this technical problem, the invention provides a kind of simulation fireplace of use biomass fuel
, it uses biomass fuel pellet, and including a body that can be placed on ground.Body includes anterior one one warming stove for energy exchange of emulational electric fireplace and rear portion for being used to view and admire；Warming stove includes a combustion box and an auxiliary equipment case.
In combustion box a burning is accommodated in the bottom close to ground
Device, burner has fuel frame plate, the side plate that is upwardly extended along fuel frame plate periphery, and a blast area being located at below fuel frame plate, and side plate surrounds above fuel frame plate and offers several air vents on combustion zone, fuel frame plate and side plate.The top of burner is provided with a heat exchange case, heat exchange case includes the front one towards emulational electric fireplace direction, one back side relative with front, one bottom surface towards ground direction, one top surface relative with bottom surface, one first side, and a second side relative with first side.A flue gas discharge opening is just offered in a flue gas inlet port, first side to being offered at burner on bottom surface.In heat exchange case provided with two row more than, each column two or more through front and back heat-dissipating cylinder, there is a piece of vertical clapboard between every two row heat-dissipating cylinder, a transverse joint is formed between the top surface or bottom surface of every vertical clapboard and heat exchange case, wherein the transverse joint difference on per adjacent two panels vertical clapboard is in top surface side or with bottom surface side；There is at least two panels diaphragm plate per between two panels vertical clapboard, a longitudinal joint is all formed between every diaphragm plate and the vertical clapboard of its both sides, wherein the longitudinal joint difference on per adjacent two panels diaphragm plate is in the vertical clapboard side of homonymy.
The reverse side of heat exchange case is provided with the back side wind pushing box that is connected with heat-dissipating cylinder, and the positive side of heat exchange case is provided with a front wind pushing box being connected with heat-dissipating cylinder, and cooling fan can rearwardly air blast in wind pushing box.
Fuel conveying mechanism and electrical equipment are accommodated in auxiliary equipment case.Fuel conveying mechanism includes hopper, and an one end is connected the feed cylinder that the other end is stretched into combustion zone, and a fuel spiral pushing bar being rotatably contained in feed cylinder with the outlet below hopper.Electrical equipment include cooling fan, the feeding motor of driving fuel spiral pushing bar, one can be into burner blast area in air blower, air exhauster, the emulational electric fireplace being connected with the flue gas discharge opening in heat exchange case first side the blown light source and motor, power supply and a power switch that use.
The beneficial effect that the present invention is brought is due to multiple row heat-dissipating cylinder and vertical clapboard and diaphragm structure with transverse joint and longitudinal joint in heat exchange case, i.e. the length of the discharge-channel hot switching path of flue gas has obtained significant increase in limited structure space, so in the case where not increasing or even reducing volume, the heat exchanger effectiveness of stove is obviously improved, and reduces the waste of energy.
