The biogas tea fixing machine is characterized in that: the heating device comprises a stove and a biogas combustion device arranged under the tea fixing roller; the biogas combustion device comprises a biogas delivery pipeline which is connected with a biogas digester and provided with a valve, and a plurality of high temperature-resistant biogas ejectors connected with the output end of the delivery pipeline; the biogas ejectors pass through the side wall of the stove to extend into the hearth of the stove; and biogas nozzles of all the biogas ejectors are arranged at equal intervals along the length direction of the hearth. The fixing machine is provided with heat by the combustion of the biogas, and the combustion cost is lower, so the manufacturing cost of tea is reduced; the main component of the biogas is methane, and generates water and carbon dioxide after combustion, so the environment is protected; besides, the combustion value of the biogas is high, so the biogas provides enough heat for the fixing machine; therefore, the produced tea has higher quality.

The invention relates to an ignition method of a boiling furnace. The method comprises the following steps of: laying hot furnace slag on an air distribution plate; laying bamboo charcoal on the hot furnace slag, and igniting the bamboo charcoal to form a charcoal fire layer; forming a micro negative pressure of minus 10 to 50Pa in a hearth; starting an air blower, so as to enable the charcoal fire layer to slightly jump and not to be buried by the furnace slag; uniformly spreading slack coal on the charcoal fire layer, and gradually increasing air quantity so as to raise the temperature of a material layer; when air output reaches the minimum air speed during normal operation, maintaining the temperature-rise speed of the material layer according to the quantity of the spread slack coal; when the temperature of the material layer reaches 600 to 700 DEG C, increasing the quantity of the slack coal and the air output to enable the air speed to exceed the minimum air speed within 5s; when the temperature of the material layer reaches 750 to 800 DEG C, remaining the addition amount of the slack coal and the air output unchanged so as to steadily raise the temperature; when the temperature of the material layer reaches 800 to 850 DEG C, starting a coal feeder to normally feed coal, remaining the air output unchanged, and adjusting a combustion situation until a flame is stabilized to be golden yellow. According to the ignition method, the ignition time is short and the one-time ignition success rate is high.

The invention discloses an aerosol fire extinguishing agent for a hand-held fire extinguisher and a preparation method thereof.
