Divide electric energy to aid in the backwater of heating biological matter shaped fuel boiler, form the integrated heating system of two kinds of regenerative resources.
For the ease of understanding that this is used for the heating system in greenhouse, the heating system for being used for greenhouse is explained below
It is bright：
Biomass shaped fuel boiler 100：Embodiments in accordance with the present invention, the biomass shaped fuel boiler 100 includes：
Body of heater 110, chain-grate 120, First air locellus 130, chimney arch 140 and Secondary Air pipeline 150, wherein, limited in body of heater 110
Burner hearth, and the side wall of the burner hearth is water-cooling wall；Chain-grate 120 is located at the bottom of burner hearth, defeated for rolling
Send fuel；First air locellus 130 be located at the bottom of chain-grate 120, for for chain-grate 120 burn oxygen supply；Chimney arch 140 is set
In burner hearth, and on chain-grate 120, burner hearth is divided into primary combustion zone and intermediate zone, and the stove
Arch 140 is in being staggered, the mixing to strengthen gas stream in the stove, heat radiation and heat smoke flowing in rationalization's stove, with up to
To catching fire in good time, vigorous burning and the purpose fully burnt；The air outlet of Secondary Air pipeline 150 be located at the chimney arch that is staggered it
Between, for auxiliary combustion.Thus, under various loads, reasonable distribution primary and secondary air ratio adjusts First air along chain-grate
The distribution of length, improves efficiency of combustion, reduces excess air coefficient, controls temperature of fuel layer, to improve boiler thermal output and prevent
Only slagging on fire grate.And burner hearth uses fin panel casing, radiant heat transfer in stove can be strengthened, reduce boiler volume, subtract
Light both weight.Meanwhile, First air, which mixes proper amount of flue gas recycled, can reduce the discharge of nitrogen oxides.Also, using control
Device processed controls the work of fuel boiler, improves the efficiency of fuel boiler, and reduces the dirty combustion things discharge of air, energy-conserving and environment-protective.
Embodiments in accordance with the present invention, the biomass shaped fuel boiler 100 further comprises：Heat-insulation layer (does not show in figure
Go out), the heat-insulation layer is arranged on the outer wall of body of heater 110.Thus, the heat-insulation layer significantly strengthens radiant heat transfer in stove, reduces boiler
Volume, mitigates both weight.
Embodiments in accordance with the present invention, the biomass shaped fuel boiler 100 further comprises：Boiler blow-down water electrical heating group
Part, the boiler blow-down water electric heating assembly is located on the supply line of biomass shaped fuel boiler, and boiler blow-down water electrical heating group
Part is connected with solar panel.Thus photovoltaic electric energy concurrent heating biomass shaped fuel boiler backwater, realization is provided multiple forms of energy to complement each other, it is ensured that
Temperature in winter greenhouse is maintained at the scope needed for plant growth.
Embodiments in accordance with the present invention, the system further comprises：Biomass block-making machine 400, the biomass block-making machine 400
It is connected with fuel boiler 100, the biomass fuel block of biomass block-making machine production is delivered to biomass shaped fuel boiler 100 and is
The biomass shaped fuel boiler 100 provides biomass molding fuel.Thus, the biomass shaped fuel boiler is given birth to low emission
Material is fuel, can be in the winter time northern area warmhouse booth heat supply using biomass energy, and can help to solve northern country
Stalk dissipate burning problem, reduce atmosphere pollution, reduction haze.Meanwhile, the carbon dioxide in the flue gas of biomass combustion discharge can
Using the carbon-dioxide gasfertilizer as chamber crop, promote plant growth.
Herein it should be noted that the volatile matter of biomass is significantly larger than coal, fixed carbon content is low, sulfur content and ash rate
General thermal coal is much lower, and calorific value is smaller than thermal coal.Using biomass as fuel, fuel enters after stove, is inwardly risen from fuel slug surface
Temperature is dried, and volatile matter decomposes release, ignition；Volatile matter fires rapidly under the cooperation of First air and Secondary Air in burner hearth
To the greatest extent, loss of the inadequacy burning for chemistry mechanics reason very little；The ignition while fixed carbon in biomass fuel block coke heats up on fire grate；
Polymerization and pore structure due to biomass block coke skeleton are enriched, and air is easy to fixed carbon diffusion into the surface, and fixed carbon holds
Easy to burn out, lime-ash structural integrity, phosphorus content is low, and unburned carbon loss is also small；Therefore it is molded the burning of biomass fuel
Efficiency high.Biomass sulfur content is low, and the maximum temperature of fuel bed is aided with partial fume recycling at 1000 DEG C or so on fire grate,
Sulfur dioxide, nitrous oxides concentration in boiler exhaust gas can reach and close in boiler Air Pollutant Emission national standard to combustion
The limit value requirement of gas boiler；Due to shaped fuel lime-ash agglomeration and sack cleaner is installed, the particle in boiler exhaust gas
Thing concentration can be less than 20mg/m3.Thus, using biomass as fuel, carry out burning using the fuel boiler of the embodiment of the present invention and add
Heat, high combustion efficiency, sulfur dioxide and nitrous oxides concentration are low, and environmental pollution is small.
