Mix through surplus waste oil in kitchen and alcohol-group fuel below and fire the test that experimentizes:
Viscosity test to the surplus waste oil in kitchen:
Kitchen surplus waste oil viscosity at normal temperatures is very big, and mobile poor, cup burns in being unfavorable for being transported to.Test its viscosity, and it is significant to its application to seek the reduction method of viscosity.
Engler viscometer is adopted in the test of viscosity, and the definition of Engler viscosity (E) is the ratio of time and 20 ℃ of following water outflow times of oil outflow under this temperature of 200ml.And commonly used be kinetic viscosity, and the relation between the Engler viscosity is:
.The cp commonly used of unit representes 1cp=0.01m
2/ s.
Utilize the Engler viscometer viscosimetric, at first, all make liquid level at this height, can on the viscosimeter chamber wall, mark for guaranteeing each experiment with being filled to certain altitude in the viscosimeter.With metering, manual time-keeping begins the placement range when opening the exit valve greater than the graduated cylinder of 200ml in the exit.Stopwatch stops timing when treating that solution rises to 200ml in the graduated cylinder, writes down the used time.So back and forth, reject and wherein to differ bigger data, get the time that 5 groups less mean value of error wherein flows out as 200ml water.
In viscosimeter, inject the surplus waste oil in kitchen, with thermometer measure and write down temperature value.Use the same method and measure the time that the surplus waste oil in 200ml kitchen flows out.The ratio of the time that the surplus waste oil in kitchen and water flow out is for the cook Engler viscosity of surplus waste oil of this temperature, is kinetic viscosity through transforming.
Change temperature, repeat to test to record the viscosity of the surplus waste oil in kitchen under different temperatures, as shown in Figure 3.As can be seen from the figure the surplus waste oil viscosity with temperature in kitchen raises and reduces, and its trend approaches the monobasic quartic polynomial.So improve the viscosity that temperature can reduce the surplus waste oil in kitchen, improve its flowability.
To the surplus waste oil thermal value measurement in kitchen:
Calorific value is the key factor of a kind of fuel quality of decision, and the calorific value of the surplus waste oil in research kitchen helps to learn its ignition temperature, confirms its scope of application.The fuel of high heating value is applicable to the occasion that requires ignition temperature higher, does not need the occasion of high-temperature too then not need the fuel of higher calorific value, can produce more pernicious gas on the contrary.
Utilizing the principle of oxygen bomb appearance calorimetric value is thermal balance.Be filled with the oxygen of 3MPa pressure in the oxygen bomb; Fuel burns therein, and oxygen bomb places among the container that fills water, and the heat that burning is produced is passed to the water in the container through the oxygen bomb wall; The temperature of water is raise, measure the water temperature variation and can obtain the heat that fuel combustion produces.The heat that unit mass fuel produces is calorific value.
Experimentation at first will be demarcated the residing system of oxygen bomb, burns in oxygen bomb with the fuel benzoic acid of known calorific value, and the heat that the benzoic acid burning of known quality produces can be known, is changing the thermal capacity that just can draw system through water temperature.In the same system of known thermal capacity, carry out thermal value measurement, repeat repeatedly to test, reject the bigger data of error, getting 5 less cell means of error is the surplus waste oil calorific value in kitchen.
Because what the direct reading of oxygen bomb appearance calorimetric value obtained is higher calorific value, and use the calorific value that low heating value is represented this fuel always in the practical application.According to the definition of high low heating value, can deduct the gasification latent heat of water and obtain low heating value by higher calorific value.
Calculate with one group of data instance: the surplus Waste-oil combustion in 1.1951g kitchen, its higher calorific value are 41660J/g, and the aqueous water that burning produces is 1.2293g.Then its low heating value is:
In like manner can calculate the Q of other group experiments
LowValue be respectively: 39134J/g, 39103 J/g, 39347 J/g, 39235 J/g, mean value are 39191 J/g.
Error analysis adopts the standard deviation formula to calculate
Relative error is 44.88/39191 * 100%=0.11%.It is thus clear that experimental error is very little, be 39191 ± 44.88 (J/g) so record the calorific value of the surplus waste oil in kitchen, be about 39.2MJ/kg.

The thermal efficiency of fuel combustion is of great importance to the utilization of this fuel, is related to its commercial value.The surplus waste oil in kitchen because viscosity is bigger, need be heated and improve its flowability in practical, commercial; Higher because of burning-point, nonflammable again, carry out commercial application so adopt with the method for the mixed combustion of alcohol-group fuel.Study the thermal efficiency that two kinds of liquid fuels mix combustion, help the transformation of burner, increase economic efficiency.
Thermal efficiency test utilizes thermally equilibrated principle; 20kg water is mixed the combustion heating through the surplus waste oil of alcohol-group fuel and kitchen; Being heated to 90 ℃ of energy needed by 40 ℃ is the known available heats that are, and measures the heat that two kinds of firing rates multiply each other and can obtain consuming with its calorific value respectively.The ratio of available heat and total amount of heat is the thermal efficiency.
It is 85% that alcohol fuel methanol content is used in experiment, and kitchen its calorific value of surplus waste oil is known.Earlier the flow of the surplus waste oil of alcohol-group fuel and kitchen is fixed on a certain value in the experiment, treats that system stability tests again.Survey water temperature with thermocouple and change, two kinds of fuel mass of electronic scale record change, and pick up counting in the time of 40 ℃, read used time, the surplus waste oil in kitchen and alcohol-group fuel consumption during to 90 ℃.
Change two kinds of flow fuel, repeated experiments.
Analyze with one group of data instance wherein:
Known test is that the calorific value of used alcohol-group fuel is Q
AlcoholBe 15.86MJ/kg, the calorific value Q of the surplus waste oil in kitchen
GroundBe 35.83MJ/kg.So the gross energy that consumes is:
; To be water rise to the heat that 90 degree are absorbed by 40 degree to available heat is:
.
The thermal efficiency is:
