Portable picnic biomass-burning warming furnace

Abstract

The invention discloses a portable picnic biomass-burning warming furnace which comprises a furnace body and a furnace hearth. The furnace hearth is arranged in the furnace body, surrounded by the wall of the furnace hearth and communicated with a feeding hopper; the lower part of the furnace hearth is provided with a grate and an ash hopper, and the upper part is provided with a burner; the upper opening of the burner is provided with a burning basin; an air preheating and flowing cavity is formed between the shell of the furnace body and the wall of the furnace hearth; and a plurality of secondary air inlet holes are disposed on the shell of the furnace body. The portable picnic biomass-burning warming furnace does not need to be provided with a smoke pipe and a fan, is compact and portable, is easy to manufacture, simple in operation, and low in production and use cost, can burn various bulk biomass such as straw and tree branches which do not need to be fine processed on the spot fully without smoking, can be used for cooking and warming and is suitable for popularization.

Description

technical field [0001] The invention relates to a stove which uses biomass as fuel to convert combustible gas, in particular to a portable biomass picnic stove which converts organic matter into combustible gas through high-temperature cracking and gasification. Background technique [0002] Energy is the basis for human survival and development. With the rapid development of social economy, human demand for energy is also increasing. A large amount of mining and use of fossil energy will pollute the environment and destroy the ecological balance. The development and utilization of clean renewable energy is imminent. Biomass is an environmentally friendly renewable energy that can be converted into gas fuel. Biomass can be converted into liquid It is an environmentally friendly renewable energy that is fueled and ranks fourth in the world's total energy consumption after coal, oil and natural gas. Biomass gasification technology is one of the effective ways to use biomass e...

Problems solved by technology

Although this furnace solves some of the shortcomings of the traditional ground pot, it produces a large amount of tar (contains carcinogens and affects the physical and mental health of users) during the combustion process; it is difficult to ignite, and the smoke is large and smoky every time it is added; the density of raw materials is relatively high. High; the combustion process is unstable (easy to turn off the flame and smoke); in addition, chimneys or blowers are generally used to speed up the circulation of air in biomass stoves, otherwise it is easy to smoke due to insufficient oxygen supply and the firepower is not strong; most of them are bulky and inconvenient to transport and Mobile; the price is high, mainly fuel that has been processed and pulverized or even compressed, the cost of use is high, the operation is inconvenient, and it is not suitable for collecting firewood on the spot, which is not conducive to promotion and popularization
