Design Of Testing System For Thermal Performance Of Stove

As a large agricultural country, 80 percent of China's population live in rural areas, with the village life can be getting bigger and bigger at present in the national proportion, the majority of energy facilities is firewood cookstoves and coal stoves, in China's rural areas.But because our country countryside area economic development backwardness, the firewood cookstoves and coal stoves' development falls behind by far of the new rural reconstruction request, carry out the high efficient, low-emission diesel-section of the firewood and coal saving stoves with the technology to promote rural areas is the focus of the work of saving energy and reducing consumption.At present, beacouse there is not have the compulsory standard request of the firewood and coal saving stoves in the market, the market products'quality are also uneven, especially many the firewood and coal saving stoves'indication lacks the essential restraint. The bad present situation of the firewood and coal saving stoves mainly to attribute to the test standards of the firewood and coal saving stoves is non-normative in our country, although the country also has the corresponding test criteria in the firewood and coal saving stoves' test to supply the reference, but these kinds of tests have only limited the firewood and coal saving stoves'test general request and some test parameter target, even many targets are carry on the determination by person's subjective factor, this is very easy to introduce the test data of the measuring error and the jamming, it's unable to carry comparison the stoves on fairly and objectively.Therefore, development a test platform that based on the national present standard for the foundation of the firewood and coal saving stove become the standard our country the market of the firewood and coal saving stoves, to realize the countryside area energy conservation to reduce a row of important measures.The article widespread investigation carries on the firewood and coal saving stove and in the foundation, summarized the existing each kind of firewood and coal saving stoves'pattern characteristic, GB6412-86, Method for testing household coal and stoves is the basis, designed and developed a tested platform based on the automatic reduction firewood and coal saving stoves, and compared between the tested the platform and the tradition manual test method, adjusted the reliability and the stability of the tested platform. This article primary coverage and the research results are as follows:1,Has carried the market research on firewood and coal saving stove in our country and studied on the development testing technology of it , based on the national standards to firewood and coal saving Stove integrated test parameters.2. Developed with automatic data acquisition and processing capacity of the provincial firewood and coal saving Stove integrated test platform. The test platform consists of weighing units, bench units, measurement unit, water unit, automatic control systems, test software components, and so on. The systems use of microcomputer operating, can collect the weight and temperature in Pot of water evaporation instantaneous changes record, Automatic water supply, temperature instantaneous change records in Furnace mouth and shell, The use of collected data to calculate the testing of key indicators and support indicators about the thermal efficiency of boilers, the average fire intensity, time of lit.3. Simulation tests the running shows that the test system can achieve the national standards set forth in the parameters of the acquisition and processing functions, and auto-complete test report output.4, Through the manual and software methods to test a specific energy-saving and straw briquette furnace, the measured section and straw briquette furnace of the indicators are in line with the general performance of appliances to test effectively. Shows that the author can test software designed in accordance with GB6412-86 family and stoves coal stoves pilot test methods and test greatly reduces the manual steps, reducing errors in the testing process.
