Biomass efficient energy-saving heat-supply circulating system

Abstract

The invention relates to a biomass efficient energy-saving heat-supply circulating system which comprises a biomass heating system (1), a biomass heat supply system (2), a preheater system (3) and a dust collecting system. A feed inlet, a smoke outlet, a water inlet and a steam outlet are formed in the biomass heating system (1). The smoke outlet of the biomass heating system (1) in the biomass heat supply system (2) is connected to the air inlets of three layers of heating tubes, the air outlets of three layers of heating tubes are connected to the smoke inlet of the preheater system (3), thesmoke outlet of the preheater system (3) is connected to the smoke inlet of the dust collecting system, the inlet of a U-shaped heating tube in the preheater system (3) is the water inlet of the preheater system (3), the outlet of the U-shaped heating tube is the water outlet of the preheater system (3), the outlet of the U-shaped heating tube is connected to water inlets of the three layers of heating tubes, and the water outlets of the three layers of heating tubes are connected to the water inlet of the biomass heating system (1). The biomass efficient energy-saving heat-supply circulatingsystem combusting biomass full-automatically to heat is high in heat efficiency and energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a heat supply cycle system, more specifically to a biomass high-efficiency energy-saving heat supply cycle system, which belongs to the technical field of biomass energy. Background technique [0002] Biomass is organic matter produced by absorbing carbon dioxide from the air through photosynthesis. It is widely distributed, available in large quantities, and is the only renewable natural fuel containing hydrocarbon components and thermal energy that can be stored. [0003] At present, it is very common to use biomass fuel for heating and cooking. However, the biomass combustion process in the existing biomass heating system is unstable, and a large amount of smoke or harmful gas will be generated during combustion, polluting the environment, and the environmental protection is poor; and the combustion efficiency is low, and the thermal efficiency is poor, generally 81%. Left and right, waste resources; at the same time, full...
