Abstract
The invention discloses a method for assessing a gas engine. The method comprises the following steps: a first step of calculating the item score of each item according to the following formula: item score=importance degree*item attention degree*item special requirement, the item attention degree being 1, 2, or 3 according to requirements; the item special requirement being 1 or 2 according to requirements; a second step of calculating the score of a single item brand of each single item in accordance with the following formula: the score of a single brand=item score*single item evaluation level; a third step of calculating the score of the total brands in accordance with the following formula: the score of the total brand=sum of the scores of a single item brand; a fourth step of comparing the score of the total brands of all the generation units, the highest score being selected as the optimal brand. The method uses a detection device and the digital evaluation method to address the difficulty of brand selection for a user, can guarantee benefits of the generation units, and optimizes investment of the user.
Description
Technical field
The present invention relates to technical field of internal combustion engines, particularly relate to a kind of gas internal-combustion engine assessment method.
Background technology
Domestic natural gas price is higher at present, and Distribution of Natural formula economy of energy benefit is on the low side, but its environmental benefit and energy
Source benefit conventional electric power generation to be far above, Distribution of Natural formula energy project mostly is municipal project.And municipal project considers demonstration effect
Benefit is many can select the efficient unit of import, and as enterprise investment, the up-front investment high expensive of import unit, and domestic unit exists
Again not as good as import unit in brand effect, therefore the most a lot of user cannot clearly select unit brand.
Summary of the invention

Method, this patent is applied to the brand of gas internal-combustion engine in Distribution of Natural formula energy project and selects, not only considers brand well-known
Degree, more carries out comprehensive digitized test and appraisal in terms of itself performance, operational efficiency and user pay close attention to direction etc..Allow user more
Select to be more suitable for the unit of oneself intuitively.
In order to achieve the above object, a kind of gas internal-combustion engine assessment method that the present invention provides, comprise the following steps:
The first step: calculating the project score of each project, formula is as follows:
Project score=importance degree * project attention rate * project particular/special requirement, project attention rate is 1,2 according to demand, or 3；
Project particular/special requirement is 1 or 2 according to demand.
Wherein, electrical efficiency importance degree is 10, and noise importance degree is 5, and flue-gas temperature importance degree is 5.
Second step: calculating the individual event brand score of each individual event, formula is as follows:
Individual event brand score=project score * single item evaluation grade.
Wherein, the single item evaluation grade of electrical efficiency: by electrical efficiency detecting system, the electrical efficiency ginseng of detection brand unit
Number, less than 35% is 1,35%～38% to be 2, and more than 38% is 3；Wherein, electrical efficiency=1Nm3Natural gas burns produced completely
Raw electricity * often spends electric heating value 860 kilocalories/1Nm3Heating value of natural gas * 100%, the electricity that combustion of natural gas produces is by voltameter
Directly read, the gas componant table that heating value of natural gas is given by gas company embodies.
The single item evaluation grade of noise: by noise detecting system, the noise parameters of detection brand unit, more than 100 are
1,80～100 is 2, less than 80 to be 3；Described noise detecting system is noise decibel tester, tests at distance sounding body 7 meters
Decibel value on the basis of.
The single item evaluation grade of flue-gas temperature: by temperature sensor detection brand unit flue-gas temperature parameter, 430 with
Down for Isosorbide-5-Nitrae 30～450 be 2, more than 450 is 3.
3rd step: calculate total brand score, formula is as follows:
Total brand score=individual event brand score summation.
4th step: relatively total brand score of all units, soprano is that optimum brand selects.
Wherein, the project appraisal of following table is farther included:
Wherein, temperature sensor is double-metal sheet type sensor；It is sticked together by the metal of the two panels difference coefficient of expansion
And form, it is placed in flue gas, along with the change of temperature, materials A is higher than another expansion of metal degree, causes sheet metal curved
Bent；The curvature of bending is converted into an output signal, and then gathers flue-gas temperature parameter.
Wherein, temperature sensor is thermocouple；It is placed in flue gas, directly measures temperature, and temperature signal is converted into heat
Electromotive force signal, is converted into flue-gas temperature parameter by electric meter.
The invention has the beneficial effects as follows: this method utilizes detection equipment and the mode of digitized test and appraisal, solves user and exists
The difficult problem that brand selects, had both ensured Benefit of Unit, had optimized again the cost of investment of user.
