Honeycomb-coal stone for tobacco leaf condensed roasting room and operation method thereof

Abstract

The invention discloses a honeycomb coal furnace for a dense tobacco barn. One side of the barn is provided with a heating chamber. The honeycomb furnace is in the heating room. The honeycomb furnace includes a furnace body and a chimney. The outer casing, the upper part of the furnace body is provided with a furnace cover, and the two ends of the furnace body are provided with furnace doors. The outer casing, furnace cover and furnace door are provided with an insulating layer made of refractory materials, and the side of the furnace body is provided with air intake and combustion-supporting holes. There is a track on the bottom surface of the hearth in the furnace body, and a coal-burning basket is set in the furnace body. The bottom of the coal-burning basket is provided with a pulley corresponding to the track. An air inlet chamber is formed between the bottom of the coal-burning basket and the bottom surface of the hearth in the furnace body. The air chamber is connected with the air intake and combustion-supporting hole, and the heights correspond to each other, so that the periodic law of coal combustion: small, medium, large, medium and small processes occur in the same combustion furnace, the baking temperature is more stable, and the baking quality is improved. Improvement, can burn a furnace of smoke after one ignition, easy to operate and reduce labor intensity.

Description

technical field [0001] The invention relates to a honeycomb coal stove and an operating method thereof, in particular to a honeycomb coal stove and an operating method thereof specially used in tobacco leaf intensive curing houses. Background technique [0002] At present, in tobacco farms in the United States, Japan and other countries, most of the dense curing rooms used are metal or plate structures, with electricity and fuel oil as the main energy source, or coal-fired boilers for heating. This type of baking furnace has a relatively high degree of automation. High cost and high cost of use. Each kilogram of dry tobacco requires 0.8-1.0L diesel and 0.5-0.8kw / h electricity. After being introduced in China, due to the high cost of baking, unstable performance, and poor flue-cured tobacco effect, it has been idled. Based on the local conditions, the stove and heating system have been greatly improved according to the local building materials and energy types, but no standar...

Problems solved by technology

[0002] At present, in tobacco farms in the United States, Japan and other countries, most of the dense curing rooms used are metal or plate structures, with electricity and fuel oil as the main energy source, or coal-fired boilers for heating. This type of baking furnace has a relatively high degree of automation. High cost and high cost of use. Each kilogram of dry tobacco requires 0.8-1.0L diesel and 0.5-0.8kw / h electricity. After being introduced in China, due to the high cost of baking, unstable performance, and poor flue-cured tobacco effect, it has been idled. Based on the local conditions, the stove and heating system have been greatly improved according to the local building materials and energy types, but no standardized production process has been formed in the application. For example, the vertical oven uses loose coal or wood as fuel, The disadvantage is that frequent manual operations are required; most of the honeycomb coal furnaces used in southern China are small burners and large coal balls, and the structure is a furnace bar or a small furnace. The double-burner burner is used in conjunction with frequent manual operations; the disadvantage of the double-burner burner is that the furnaces on both sides are ignited and burned alternately. When the coal on one side is almost exhausted and the coal on the other side is not burning vigorously, temperature fluctuations are prone to occur.
