Study On Combined Operation Of Multi-sources Technique In Huhehaote City

Combined operation of multi-sources is the developing current of centralized heat-supply system. But how to combined operation and what significance they have, is still the problems that puzzled a lot of expert, scholar, technical personnel of the business enterprises demand discuss thorough. This article calculated and analyzed the technique of the twin-sources combined operation in the city of Huhehaote, stated the concretely exercises and actual result that had acquired.This text is total be divided into three big part.The first part mainly discussed the necessity of this combined operation. Analyzed the basic parameters including weather, heating load, heat source, and stated the design tenet and thereunder. Ulteriorly stated the developing actuality of centralized heat-supply inside and outside the country, analyzed the problems of centralized heat-supply inside the country, advance the necessity of centralized heat-supply reformatory.The second part thoroughly investigated the basic datum of this project, mainly stated the heating load. Based these dates, something like parameters of heating medium, installation fashion of heating pipeline, pipe material, anticorrosion protection and insulation, construction fashion of heating pipeline, pressure test standard, purging scheme can be confirmed. Then make the hydraulical analysis by stages based the design temperature of supply and return water, flow-resistance characteristic co-efficient of pipeline, specific pressure drop. Draw the sketch of the hydraulical analysis and the pressure diagram. Then stated the regulation fashion and drawing the temperature adjustment curve.The third part discussed the benefit of this combined operation of multi-sources in environment and energy saying, and stated some problems that should notice in the construction of the engineering, circulate and manage.
