Research And Calculation Of The Heat Reservoir Heating System Of The Electric Boilers

The object to study in this paper is the electric heat reservoir boiler,which is used to supply heat water and bask for the resident population.The use of the system define the character of the output medium with the lower request on quality and parameter,at the same time,it ask the boiler should has the higher character on the respect of the cost,reliability,economy,and so on.Hence,the paper carefully design and study the system for the choice and design of the boiler core heating componet,the lay of the heat exchanger,the working status of the heat reservoir equipment,the adjustment and control mode of to supply heat water.the study work mainly include underside some contents,forexample:1. To confirm the heat medium parameter to adapt the requirements of the most of the heating equipments and to design the instruction of the boiler and heat reservoir as simple as possible.2. The purpose of making a reasonable design is to improve the capability and to postpone the life of the heating component by to analyse and compare all kind of materials to make the heating component,and to compute carefully the construct dimension of heating component to base on the practical conditions.3. The paper analyse the lay formats of the different heat exchanger and compute the surface temperature of the electrical heating tubes,the relation between the flow resistance and the flow speed,the working temperaure of all parts of electrical heat component.By above analysis,to control every relative parameter during reasonable range in order to delay the growth speed of the furring and to reduce the electrical consume of the water pump.4. The paper confirm the proper adjustment method of the quantity of the heat provided in order to suffice the needs of the needs of the heat balance between the heat supply and the heat consume by the heat balance analysis method during the low load.The purpose is to ensure the effect of the heat,to avoid the waste of energy and to save the running cost farthest.5. To study the intellectualized control system with the entirely/half automatic functional in order to make the entire heating system to have the manual operation and the interlock protect functions when the system go wrong.
