Energy is the lifeblood of the development of the national economy and an important material basis for improving people's living standards. With the development of national economy, the demand for energy is increasing. China is a country rich in energy resources. Due to its large population, the per capita energy output is still very low, about one third of the world average. Therefore, our country adopts the energy policy of both development and conservation, and puts energy conservation in a very important position. Due to the low level of energy utilization in China, there is great potential for energy conservation.
Experimental electric furnace and industrial boiler are one of the most energy consuming equipments in China, and the energy consumption accounts for about one third of the national energy consumption every year. The energy consumption of experimental electric furnace and industrial boiler is to produce secondary energy steam or hot water. Steam or hot water is sent to all kinds of heat equipment through the heat pipe network. Boiler, pipe network and heating equipment constitute the thermal system, and the energy utilization rate of the system is equal to the product of boiler thermal efficiency, pipe network thermal efficiency and heating equipment thermal efficiency.
It can be seen that the boiler energy consumption is not only determined by its thermal efficiency, but also by the energy utilization rate of the thermal system. Therefore, saving energy consumption of industrial boiler must be considered from boiler, pipe network and heat equipment.
The main reason for the low efficiency of experimental electric furnace and industrial boiler is that the boiler capacity is too small, which reduces the energy utilization rate. Our country's experimental electric furnace and industrial boiler are mainly used for heating, heating and living. Many enterprises and institutions only pay attention to the technical transformation of the boiler itself to improve the output and thermal efficiency, but pay less attention to the comprehensive utilization of energy, and ignore the leakage heat dissipation of pipe network and heat equipment. As a result, the bigger the boiler is, the higher the thermal efficiency is, but it consumes a lot of energy, Energy efficiency is not high.
因此，要提高鍋爐的能源利用率，除了要提高工業鍋爐本身的熱效率外，還要實行工業鍋爐的供熱系統節能、軟件節能與硬件節能相結合的全 方 位節能策略。
Therefore, in order to improve the energy efficiency of the boiler, in addition to improving the thermal efficiency of the industrial boiler itself, but also to implement the industrial boiler heating system energy-saving, software energy-saving and hardware energy-saving combination of all-round energy-saving strategy.
