Abstract

The invention provides a boiler heating system and a boiler heating main system. The boiler heating system comprises a main heating subsystem and an auxiliary heating subsystem; the main heating subsystem comprises a water tank expansion container, a boiler and a heating pipeline, water from the water tank expansion container is heated to set temperature through the boiler, and then the heated water is output to a water inlet of external heating equipment through the heating pipeline; a water outlet of the heating equipment communicates with a warm water recycling water inlet; the auxiliary heating subsystem comprises an auxiliary heat input port which communicates with an external recycling heat source, an external auxiliary heat pipeline which communicates with the auxiliary heat input port, a first heat exchanger arranged on the external auxiliary heat pipeline and an auxiliary heat output port which communicates with the external auxiliary heat pipeline; and the first heat exchanger is used for transmitting heat of the external auxiliary heat pipeline to the heating pipeline. According to the boiler heating system and the boiler heating main system, energy consumption of the boiler system is reduced, and energy conservation performance and economical efficiency of the heating system are improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler heating system and a main boiler heating system. Background technique [0002] A boiler is an energy conversion device that converts the fuel input into the boiler into steam, high-temperature water or organic heat carrier with certain heat energy. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. [0003] In the existing boiler system, liquefied natural gas or liquefied petroleum gas is burned, and the water in the pipeline is heated through a heat exchanger; the heated water is directly used for heating on the one hand, and can be heated through a special exchanger on the other hand. Water pipes are used to provide hot water to users. However, the...
