Biomass semi-gasification heating system

Abstract

The invention relates to a biomass semi-gasification heating system. The biomass semi-gasification heating system comprises a biomass semi-gasification furnace, an energy-saving water tank, a heat exchanger, a chimney and an air pre-heating pipe. The biomass semi-gasification heating system organically combines the biomass semi-gasification furnace, the energy-saving water tank, the chimney, the air pre-heating pipe and the indoor heat exchanger together, the combustion and reverse combustion technology is fully used in the design of the biomass semi-gasification furnace, a water cooling wall forms a hearth, the design concept that the air pre-heating pipe conveys the needed air is adopted, the energy-saving water tank is designed into four areas, the structure that water cooling pipes are communicated with the related areas is adopted, and the design of the whole system accords with the concept of energy conservation, so that the biomass semi-gasification heating system is not only low in production, manufacturing, use and maintenance expense, but also convenient to popularize in rural areas. The biomass semi-gasification heating system overcomes the defects of a common heating furnace and a common biomass gasification heating furnace, and improves the effective use efficiency of biomass energy.

Description

technical field [0001] The technical solution disclosed by the invention relates to a heating system, in particular to a biomass semi-gasification heating system. Background technique [0002] At present, the equipment used for heating in rural areas of our country mainly includes the following categories: first, household appliances that use electricity as energy, such as air conditioners, electric mattresses, electric heaters, etc.; second, self-made hot water heating systems that use coal as energy; Third, heating stoves that use biomass raw materials as energy. [0003] The first method is not easy to promote in the current rural areas of China, the main reason is that the economic cost is relatively high; the second method uses coal as raw material for the stove and self-made hot water heating system, which is suitable for coal-producing areas and their surrounding areas, otherwise use The cost is also high, and coal is a non-renewable fossil energy, and it will produce...

Problems solved by technology

[0004] However, there are some problems in the use of existing heating equipment using biomass as raw material in rural areas: first, the gasification and combustion process of biomass is unstable, and a large amount of smoke or harmful gases will be generated during combustion, polluting the environment; The efficiency is low, which wastes resources; the third is that the problem of tar production during the combustion process cannot be solved, and the pipe network will be blocked after a long time; the fourth is that the furnace design is relatively complicated, which is not conducive to popularization
