The specific embodiment
For understanding better the utility model, below in conjunction with accompanying drawing the utility model is further described, but embodiment of the present utility model is not limit so.
As shown in Figure 1, 2, a kind of combined type gas-combusting stove for Chinese meal energy-gathering device comprises burner hearth 1, connector 2, unit energy collecting plate 3, iron pan 4 and gas burner 5; Burner hearth 1 is the columnar structured of upper end open, and the upper end open place is provided with iron pan 4, and columnar structured bottom centre is provided with gas burner 5, and frame type structural base or sidewall are provided with exhaust outlet, also has connector 2 on the sidewall of burner hearth 1; As shown in Figure 3, unit energy collecting plate 3 is fanning strip, and fanning strip two arc sections are respectively equipped with connector 2, and polylith unit energy collecting plate 3 interconnects or is connected with connector 2 on the sidewall of burner hearth 1, forms the pot bottom-shape cumulative faces of different sizes.
The material of unit energy collecting plate 3 is the cordierite radiation ceramic that the Jiangxi Province intelligent special cermacis of Pingxiang City gold Co., Ltd produces, the specific heat capacity of this material is 836-1000J/ (kgK), it can absorb the heat of hot waste gas and the heat radiation that iron pan does not use well, but this material not yet finds to be used for gas kitchen ranges at present.In addition, the thermal emissivity rate of this material is 0.95-0.98, can carry out post bake to the heat that has absorbed with thermal-radiating form to iron pan, improves the heat utilization efficiency of gas-combusting stove for Chinese meal.The unit energy collecting plate scribbles VK-TC03 type low-E (0.55-0.6) coating that Hangzhou ten thousand scape new material Co., Ltds produce towards the one side of burner hearth bottom, and is high temperature resistant, nontoxic.Low-E coating can play insulation, reduces the effect that heat radiation is run off, so that the unit energy collecting plate can carry out directed post bake.This element energy collecting plate is covered with pore, aperture diameter is 1.2-1.8mm (aperture diameter is preferably 1.3-1.6mm), pitch-row is 1.6-2.1mm, the porosity of unit energy collecting plate is at 54%-65% (volume of the pore of unit energy collecting plate and the ratio of cumulative volume), unit energy collecting plate specific area is high, increase the contact area of unit energy collecting plate and hot waste gas, augmentation of heat transfer.Because the unit energy collecting plate is low pressure towards a side of burner hearth bottom, opposite side is high pressure (a large amount of hot waste gas is arranged), hot waste gas not cracked ends pore goes out from high pressure one side toward low pressure one effluent, under this small-bore, the flow velocity of hot waste gas increases, in the hole, form turbulent flow, strengthen the convective heat-transfer coefficient of hot waste gas and hole wall, be conducive to the hole wall absorbing heat.Again because the porosity of energy collecting plate is high, material is high thermal conductivity coefficient high specific heat capacity material, energy collecting plate just can absorb a large amount of heat of hot waste gas in the short time, its temperature will be rapid rising, according to Si Difen-Boltzmann's law, the radianting capacity of object is directly proportional with the biquadratic of object temperature, the unit energy collecting plate just has very high radianting capacity, sends high-intensity heat radiation, and iron pan is carried out post bake.In addition, energy collecting plate with high radianting capacity be to around carry out radiation, the utility model only utilizes it that iron pan is carried out radiation, reduce unnecessary loss, so the low-E coating that we simultaneously scribble towards burner hearth bottom at energy collecting plate is to reduce the consumption of this part, so that the radiation heating of unit energy collecting plate is more efficient.
As shown in Figure 4, gas burner 5 sends heat radiation (line style arrow), and iron pan 4 is heated, and the heat radiation (line style arrow) that part is not absorbed by iron pan 4 is reflected back iron pan 4 by unit energy collecting plate 3, and it is carried out post bake.The flow through pore of unit energy collecting plate 3 of hot waste gas (blank arrow), most of heat is absorbed, and changes into heat radiation (black arrow) iron pan 4 is heated, and then waste gas (blank arrow) is discharged through the exhaust outlet of burner hearth 1.
According to the method for testing of CJ/T3030-1995 " cook a meal and use gas big kitchen range " defined, to adopting a kind of combined type gas-combusting stove for Chinese meal of the utility model energy-gathering device and not adopting the gas-combusting stove for Chinese meal of this energy-gathering device to carry out thermal efficiency contrast experiment.Both adopt liquefied petroleum gas (gaseous-pressure: 2.8KPa, the combustion gas low heat value: 101.41MJ/m of same quality
3, Wobbe index: 84.41MJ/m
3, combustion potential: 46.0) respectively to water (specific heat capacity Cp:4.2 * 10 of 4.0kg
3J/kg) heat, temperature is elevated to 71.0 ℃ from 26.0 ℃, the amount of consumed gas that adopts the gas-combusting stove for Chinese meal of this a kind of combined type gas-combusting stove for Chinese meal energy-gathering device is 25.0L, and the amount of consumed gas of the gas-combusting stove for Chinese meal of a kind of combined type gas-combusting stove for Chinese meal of the utility model energy-gathering device that does not adopt is 29.0L.(thermal efficiency=(temperature that the quality of specific heat of water appearance * water * water raises)/(amount of consumed gas * combustion gas low heat value * (the standard state coefficient of heat flow=0.9241)) its thermal efficiency is respectively 32.3%, 27.8%, has improved 16.2% by converting.If by the former gas-combusting stove for Chinese meal consumption gas 4.725m that per hour works
3, gas price is 6 yuan every cube, works every day 5 hours, the utility model device is installed can be saved 23 yuan (4.725 * 5 * 6 * 16.2%) every day, just can save appreciable expense over a year.Can find out that from above-mentioned test this gas-combusting stove for Chinese meal energy-gathering device is really effective, improve the thermal efficiency of gas-combusting stove for Chinese meal, energy savings.
