The Design And Improvement Of SHL20-1.6-Aâ…¡ Boiler

Ensure the safe operation of the boiler, and save energy, reduce running cost, is the enterprise safety management and cost management indispensable means. Are deposited in the factors that affect the safe operation of the boiler, the problem is a very prominent problem, cause certain influence to the enterprise. Make safety accidents more, increased operating difficulties, resulting in wasted fuel, exhaust smoke temperature is on the high side, increased operating costs. Even stop the furnace, for to clean up the dust, and make the production gas is difficult to guarantee. Therefore measures must be taken to reduce the tail of formation of heating surface, to ensure the safety of boiler, energy saving, efficient operation.Author first consult a large number of related literature, combined with years of experience in boiler operation management, analyzes the specific system of boiler, the operation principle of boiler subject specific system structure and formation mechanism of heating surface, analyzes the influence of formation of related parameters, is proposed in does not affect the enterprise production conditions as far as possible to solve the boiler tail heating surface dust and reduce the exhaust temperature of the boiler. For some firms that choose SHZ type boiler dust problems in the operation of the system analysis, determine the cause of formation, through the analysis shows that the model is the main reason of the boiler to produce heavy tail smoke speed is too low, to counter the problem of low smoke speed, using the test method of the comparative study.The first step of the NO.1, NO.2, two parts of boiler economizer structure was improved, and observe the improved degree of soot formation, contrast, found that two electric furnace dust decreased significantly, economizer smoke speed increase, exhaust smoke temperature is reduced, equipment to safety running. The second step of NO.3 boiler from the design main body, and add convection bank area partition and fold smoke plate method. Contrast and found that the improved structure become complex, convection bank smoke speed increases, exhaust smoke temperature is reduced, the effect is better than NO.1,NO.2 boiler, the test results show that the designed improvements on boiler NO.3 square method can better solve boiler soot formation. The third step of NO.3 boiler other auxiliary components, further improvement economizer structure was improved, filter tube material for replacement, replace induced draft fan impeller, test results reach the expected effect, dust problem is resolved.Improved through theoretical analysis and experimental results of analysis, this paper puts forward the design of this type of boiler in the future to consider and pay attention to the details of the problem, the design of the boiler in the future and has certain reference value and operation management, for the future design efficient, safe, stable and good boiler equipment foundation of energy saving and environmental protection.
