Biological-material-tall stove

Abstract

This invention relates to a biological material ball stove including a fan, a secondary wind pipe, a valve, a flowmeter, a supply pipe, a gasification agent pipe, a loop air pre-heating chamber, a loop air conduction chamber, a stove head, a stove body, a heat preservation layer, an inner container and biological material balls, in which, the upper part of outside of the stove is a water tank made of stainless steel, the fan is connected with the loop air pre-heating chamber at the bottom of the hearth via a gasification agent pipe, the heat preservation layer, the inner container and the hearth are orderly placed in the body, a grate is under the hearth and the stove head is above it, the loop air conduction chamber is at the bottom of the head, the secondary wind pipe and the chimney are at the outside wall of the conduction chamber with a stage along the internal wall for placing a stove cover.

Description

technical field [0001] The invention relates to a biomass application field, in particular to a biomass pellet furnace. Background technique [0002] my country's thermal energy mainly relies on natural gas, petroleum liquefied gas, and coal. Due to the slow economic development in rural areas, firewood and straw are mainly used as thermal energy. According to the statistics of the International Energy Agency, if the current development continues without restraint or waste utilization, then the lifespan of these three energy sources on the earth for human exploitation is only 40 years, 50 years and 240 years respectively. Forty or fifty years, from the perspective of human history, is really very, very short. [0003] For thousands of years, rural areas have been using traditional earthen stoves to burn firewood and straw, which increases labor intensity and resource usage, which is a waste from the outside. Although coal and liquefied petroleum gas are now being used in r...

Problems solved by technology

[0004] In recent years, some household or small-scale biomass gasifier devices have appeared. However, this technology is not mature enough. It often occurs burn-through phenomenon during use, the combustion time is short, cannot continue to burn, the gas supply is impure, and the combustion is not good. Adequate, low thermal efficiency, long start-up time of cold furnace, large fuel consumption, poor energy-saving effect, serious environmental pollution, especially all small biomass gasifiers use granular gasifiers, and it is difficult to export gas from the furnace , the content of fly ash is high, the air duct is easy to be blocked, and the fly ash is mixed with the tar that is difficult to dispose of, the pipeline will undoubtedly be blocked, and the production of granular raw materials by scattered farmers will also increase additional costs. There is a lot of smoke generated during work. At this time, when the cover is removed and the material is added, the smoke will inevitably leak out, which will cause energy loss and operational troubles, resulting in interruption of cooking and even affecting the physical and mental health of the cooks.

Therefore, many gasifiers are in non-working or semi-working state, causing direct economic losses to farmers, so there is still much room for improvement in this field
