The Index Evaluation System Research Of Energy Saving Operation To The Centreal Heating Boiler Room

In the north of China, the way of heating-supply to city in winter, central heating boiler room heating 82%, the coal-fired boiler accounts for about 80% of the total boiler. However, the boiler thermal efficiency is generally low. According to statistics, in China, the comprehensive energy efficiency is just 35% ~ 55%, boiler’s energy waste has been one of national problems to be solved. At present our country for central heating boiler room is lack of scientific and reasonable evaluation system of energy conservation, evaluation method and the quantitative evaluation index. Therefore, this passage has established the central heating boiler room energy-saving operation evaluation index scientifically, and using the analytic hierarchy process to determine the index weight, using the basic principle of linear weighted comprehensive evaluation of boiler energy conservation operation, the energy-saving evaluation provides a basis for the boiler enterprise.Boiler energy waste almost in smoke heat loss, incomplete combustion heat loss of solid and gas and ash, the heat loss of boiler itself and the physical heat loss. These losses caused the fact that the boiler thermal efficiency is generally low at present. This article think from the perspective of qualitative and quantitative, according to the boiler energy loss in the direction and summary out 10 indexes evaluation on the performance of the boiler’s energy saving.Fuzziness of the qualitative index and definiteness of the quantitative index that decided to use analytic hierarchy process to determine the index weight is one of the best ways. On the one side, the scientific theory has certain persuasive, on the other side, the weight reflect the decision-makers’ purpose. Hand together the established qualitative indexes and quantitative indexes by using the weighted method to evaluate the energy level, and give the energy-saving level.Using the established index system work out the corresponding software that is convenient for enterprises self energy-saving evaluation, also provides a shortcut to government regulators. The software not only reflected the energy level of one boiler, but also proposed a certain direction to the enterprise for energy-saving reconstruction from the missed points.Based on a large number of investigation and measurement of Jilin province on the basis of the boiler room, put an example of one central heating boiler room in Changchun, through the data of field research and collection, scientific experiments calculation, and making use of the convenience of software validation index system of scientific, practicability and simplicity.
