Modification Of SHL20-13-A Type Steam Boiler And The Application Of Computer Fuzzy Control System

Changing single heating steam boiler into hot water boiler is a very important measure for saving energy. The steam boiler is transformed into the advantage of the hot water boiler, first, can reduce loss of heat of the steam heating pipeline system and the changing the loss of heat of heat transmission equipment; Second, heating range is great, the heating is effectual. Third, system operation is direct, simple, it is safe and reliable for the system to run, the maintenance cost is low. The steam boiler is transformed into a hot water boiler, is pressed the components and can all basically be utilized originally, it needn't do more change either to burn the system, the work load is reduced, very economic; Through practice for many years, it is feasible technically that the steam stove is made into the hot water boiler.This thesis has mainly introduced the steam boiler of 2 sets of Model SHL20-13 from steam boiler to technological transformation of boiler of hot water, have on of the scheme the main circulatory system of the boiler and systematic water circulation of coal device of province transform choice and demonstration of the scheme, calculate the conceptual design which has finished water circulation transformation through heating power and water motive force, and convection restrain water circulatory system carry on sub cooling seethe with excitement, check, to keep component go on intensity check transformation correctly, check and calculate the emission of the relief valve, find out the boiler computing technology of amount of coal used of roller chain, calculate in economizing on coal amount after finishing the boiler transformation.The Computer Fuzzy Control system can collect all of parameters of operating boiler, and Dynamic Optimize all of the parameters by controlling Wind fuel ratio. This system can meet requirements of the boiler at different time. It can keep the operating in the best case. Not only Improve the Efficiency of the boiler, but also make the staff in better Conditions and make the Labor intensity lowerAfter changing the boiler and the control system, The operation of the boiler become more safely and strongly. It can save o lot of energy.
