Title:
HEATING SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/114727
Kind Code:
A1
Abstract:
The present disclosure relates to a heating system and a control method therefor. The heating system comprises: a combustion device; a main heat exchange device arranged on one side of the combustion device, wherein the main heat exchange device can exchange heat with the combustion device; a liquid return pipe connected to a liquid intake end of the main heat exchange device; a liquid output pipe connected to a liquid output end of the main heat exchange device; and a heat exchange structure, wherein the liquid return pipe and the liquid output pipe selectively exchange heat by means of the heat exchange structure. According to the heating system, a liquid in a main heat exchange pipe exchanges heat with a liquid in the liquid output pipe by means of the heat exchange structure, such that a liquid output temperature of the liquid output pipe can be reduced while the liquid in the main heat exchange device is kept at a higher temperature, so as to meet a preset temperature requirement. Flue gas is also kept at a higher temperature so as to prevent the flue gas from condensing on the main heat exchange device.
