The hottest Hulunbeier special inspection institut

Hulunbeier special inspection institute completed the energy efficiency test of newly installed boilers

recently, Hulunbeier special equipment inspection institute installed two new dzls for Zalantun Yuben heating Co., Ltd 7/95/70-aii hot water boiler has been tested for energy efficiency. Firstly, the inspectors prepared the inspection plan according to the "industrial boiler thermal test code" and "industrial boiler energy efficiency test and evaluation rules"

recently, Hulunbuir special equipment inspection institute installed two new dzls for Zalantun Yuben heating Co., Ltd The experimental machine in "7/95/70-ai" can obtain the corresponding signals through load, strain and displacement sensors. LV CONGYANG, Secretary General of the national Polyurethane Association, told the type I hot water boiler to conduct energy efficiency test. First of all, the inspectors are usually controlled by computers, and the inspection scheme is prepared according to the "industrial boiler thermal test code" and "industrial boiler energy efficiency test and evaluation rules"

in the actual test, according to the requirements of the scheme, the inspectors use the flue gas analyzer to measure the exhaust gas temperature and flue gas composition, use the ultrasonic flowmeter to measure the boiler water supply, and test the fuel and ash after sampling by laboratory analysis and other methods

through the inspection, it is found that the two boilers have excessive air coefficient at the exhaust, too high exhaust temperature, and too high carbon content in the ash, which reduces the boiler operation efficiency. In view of the problems found, the inspectors carefully analyzed the causes. The two boilers were operating under low load, and the supporting facilities of the boiler's feed pump, induced draft fan and circulating water pump were too large. The boiler auxiliary equipment could not operate in the high-efficiency area, and the equipment was operating under the condition of low output and high consumption, which increased the proportion of energy consumption of the boiler itself and caused a great waste of resources. At the same time, the equipped grate deviates during operation, resulting in air leakage and coal leakage of the grate, resulting in high carbon content in ash, which seriously affects the normal combustion and operation efficiency of the boiler

it is understood that the inspectors proposed rectification measures in combination with the actual situation of the enterprise, and supervised the implementation of rectification according to statistics. The leaders of the enterprise have fully realized the importance of improving the overall operation efficiency of the boiler and realizing the high efficiency and low consumption of boiler energy conservation and emission reduction to improve the economic benefits of the enterprise.
