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

Abstract

The present invention discloses a honeycombed coal stove for flue-curing barn. It is characterized by that in one side of said flue-curing barn a heating chamber is set, the honeycombed coal stove is placed in said heating chamber. Said honeycombed coal stove includes stove body and chimney, said stove body includes external shell made up by using angle-iron and iron sheet, the top portion of said stove body is equipped with a removable lid, and two ends of said stove body are respectively equipped with a fire door, and the external shell interior, removable lid interior and fire door interior are respectively equipped with heat-insulating layer made of fire-proof material. Besides, said invention also provides the concrete operation method of said honeycombed coal stove.

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.
