Reverse-burning bio-straw briquette heating and cooking dual-purpose furnace

Abstract

Provided is a reverse combustion type biological straw compressed block heating and cooking dual-purpose furnace. The interior of a furnace body is separated into two cavities, respectively, a furnace hearth and a reverse combustion flue through a water jacket, and heat absorbing water tubes are arranged in the flue; the furnace hearth is divided into three layers, the lower layer is an ash removing chamber, the middle layer is a combustion chamber, the upper layer is a cooking heating chamber, and the three layers of structures are sequentially communicated; the combustion chamber is communicated with a primary air port, an upper layer furnace grate and a lower layer furnace grate are arranged in the combustion chamber, the upper layer furnace grate is in a turning type, the lower layer furnace grate is fixed, the ash removing device is installed on the fixed furnace grate, and an ash hopper is arranged below the fixed furnace grate; a gate used for controlling the furnace hearth to be used for cooking or heating is arranged above the flue, and a feed port and a secondary air port are formed in side faces of the furnace hearth; the water jacket is installed between the furnace hearth and the outer wall of an iron sheet, and the water jacket is communicated with two rows of heat absorbing water tubes. The furnace is provided with the gate and achieves the dual purposes of heating and cooking; the double layers of furnace grates optimize the internal structure of the furnace hearth, and proper combustion height is set; the furnace is small in occupied area, simple in structure, capable of saving energy, environmentally friendly, high in combustion efficiency and suitable for countryside and the field of life of outdoor cooking.

Description

technical field [0001] The invention relates to a civil stove, in particular to a stove for burning biomass briquettes such as straw and sawdust. [0002] Double-grate reverse-burning biological straw briquette heating and cooking dual-purpose stove. Background technique [0003] Biomass is a kind of energy that can develop in harmony with the environment and has great potential for development. my country is a large agricultural country, and the agricultural population accounts for more than 70% of the total population. The energy used in rural life mainly depends on straw and firewood. According to statistical data, more than 65% of the total energy consumption in rural areas is biomass energy. In 2013, the total annual output of straw in my country reached 722.322 million tons. The scientific and rational development of crop straw biomass energy has broad development prospects in my country. [0004] At present, the stoves using crop stalks as fuel used in the vast rura...

Problems solved by technology

[0004] At present, the stoves that use crop stalks as fuel in the vast rural areas of our country are generally only used as cooking tools. They have simple structure, single function, low energy utilization efficiency, serious pollution and serious energy waste.
