Application Of Electric Heating Technology In Central Heating System To Improve Economy Of Heating

With the gradual improvement of environmental protection work in Beijing,Tianjin and Hebei,the heating industry in North China has started the replacement of fuel for coal-fired boilers.Other clean energy combustion heating is used to replace the energy structure previously used as a major source of coal.At present,the industry is mainly using natural gas as a substitute for clean energy,and is being implemented in a large area.But the high price of scarce resources in China resulting in natural gas,high risk and natural gas are stored using the combustion heating business characteristics and current problems of central heating system,also plagued the reformed operation.At present,as a heating research direction,electric heating has received widespread attention in the heating industry because of its flexible heating mode,low cost and easy to measure the energy nature.However,due to the current cost of electricity,high prices and the limited capacity of the distribution system and other restrictions,it can not be widely applied and extended.In this paper,the central heating system,which is widely used in the heating industry,is put forward.The auxiliary power supply equipment is added to the heating branch.The net two times the maximum heating power is greater than the output power of the heat exchanger,increase heat output capacity in some areas,and even without influence on the premise of improving the heating effect of the system,reducing the overall cost of operation of heating system.If the operation is economically and technically feasible,it will greatly increase the proportion of electric power,clean energy,and heating in the overall heating system.But due to the equipment transformation for this way is not complicated and the cost is low,and not on the current huge heating network has been changed for many of the large central heating enterprises to reduce emissions and energy transformation efficiency to enhance the transformation of the old system provides a can.
