A method of using a system capable of improving the heating capacity and heating temperature of a power plant

Abstract

The invention discloses a method for using a system capable of improving the heating capacity and heating temperature of a power plant, comprising a steam-type ammonia absorption heat pump, a steam-type lithium bromide absorption heat pump, a condenser and a regulating valve. The hot water inlet and outlet of the steam type heat pump is connected with the steam type lithium bromide absorption type heat pump, one end of the steam type lithium bromide absorption type heat pump is provided with a primary return pipe, and the water pipe connection between the steam type lithium bromide absorption type heat pump and the condenser A regulating valve is provided. In this invention, a steam-type air source ammonia absorption heat pump unit and a steam-type lithium bromide heat pump unit are arranged in the hot water pipeline of central heating, so that both devices and power plant steam are used as driving heat sources, so that it is convenient to obtain low temperature from the air. Compared with the traditional method of using steam to heat the heat supply and return water in a new boiler room to improve its own heating capacity and heating temperature, it improves the economic benefits of heating, and at the same time increases the heating temperature.

Description

technical field [0001] The invention relates to the technical field of energy technology devices, in particular to a system and a use method that can improve the heating capacity and temperature of a power plant. Background technique [0002] With the development of urban economy and population growth, the heating load of northern cities has increased sharply, and due to the different heating methods of residents, higher requirements have been placed on the heating temperature of power plants. The main equipment of the existing power plant has been fixed, and it is difficult to meet the heat demand of users according to the conventional operation method. Only by building a new boiler room and using steam to heat the traditional way of heating and returning water to improve its own heating capacity and heating temperature. Power plants provide heat to users by directly heating hot water with steam. In this process, it is only the energy transfer of fuel. Under the background ...

The main equipment of the existing power plant has been fixed, and it is difficult to meet the heat demand of users according to the conventional operation method. Only by building a new boiler room and using the traditional method of steam heating and returning water to improve its own heating capacity and heating temperature

Power plants provide heat to users by directly heating hot water with steam. In this process, it is only the energy transfer of fuel. Under the background of building a conservation-oriented society, the economy of this method is getting worse and worse. How to make full use of it? Using the existing conditions to improve the heating capacity of the power plant and increase the heating temperature as much as possible has become the focus of the society's increasing attention
