Embodiment Construction
[0025] As shown in Figures 1 to 4, an embodiment of the present invention includes a core body 1, and the core body 1 includes an inner core 2 and a core sleeve 3, and the upper end of the inner core 2 is connected to the upper end of the core sleeve 3 through an annular end piece 4. Connect to form an annular cavity 5 with an open lower end, the upper peripheral wall of the inner core 2 is provided with several secondary air intake holes 6, the lower side of the inner core 2 is provided with a firewood support frame 7, and the lower end of the inner core 2 is provided with an inlet Air volume adjustment device 8. Its combustion principle and operation procedure are as follows: First, firewood is placed from the upper opening of the inner core 2. The amount of firewood does not exceed the setting height of the secondary air inlet hole 6 on the wall of the inner core 2, and the firewood is ignited from the upper opening of the inner core 2. At the same time, the lower end of th...

The invention relates to a furnace core of a firewood gasification furnace. The furnace core comprises a core body, the core body comprises an inner core and a core housing, the upper end of the inner core is connected with the upper end of the core housing through an annular end piece to form an open ended annular cavity, a wall on the periphery of the upper part of the inner core is provided with a plurality of secondary air inlet aperture gaps, a firewood supporting frame is arranged on the lower side of the inner core, and an air inlet volume adjusting device is arranged at the lower end of the inner core. The invention has the improvement that the secondary air inlet aperture gaps are three to six circles of annularly and uniformly distributed round holes. The invention has simple structure and low production cost, the secondary combustion adopts a natural air inlet way without auxiliary equipments of an air blower, a purifier, etc., and the invention is characterized in simple operation and convenience for adjusting the fire force, thereby being suitable for various furnaces, in particular suitable for being promoted in rural families. The invention is also suitable for field investigation and travel if being produced to be a small furnace, the fuel source is wide, the thermal efficiency is high, the firewood can be saved by above 70 percent compared with the conventional combustion way, and the invention has the effects of smokeless combustion, low emission, sanitation and environmental protection.
Description
technical field [0001] The invention relates to a furnace core of a gasification furnace using firewood as fuel. Background technique [0002] The firewood gasification furnace of the prior art adopts incomplete combustion to pretreat the firewood to produce combustible mixed gas, which is then introduced into the furnace mouth for secondary combustion and heat supply, such as the numbers 02213624.x, 02222750, 4, The Chinese patent of 02291929.5 is equipped with blower, purifier and other structures mostly, and some also need to be equipped with equipment such as pulverizers and briquetting machines for pre-processing fuel, and some cannot add fuel (residues need to be removed after filling up a batch of charge). Reignition), its complex structure, high cost of use, inconvenient operation, the tar produced in the purification process often leads to secondary environmental pollution, is not suitable for families, especially rural families.
