In order to make vegetables and fruits available for the morning market, heating facilities are generally used in the solar greenhouses, which are generally artillery stoves. The facility uses 6-8 tons of clean coal, the production cost is high, and the pollution is serious. In order to reduce costs, save energy, reduce pollution, and increase farmers' income, I stand to promote the use of hot blast stoves. The facility uses 1.5-2 tons of refined coal, which has a significant effect on warming. Hot blast stove advantages: 1. Under normal use conditions, one hot blast stove can be used instead of four shell bomb ovens to ensure that the 56-meter greenhouse minimum temperature is 10°C or more. 2. Under normal use conditions, the 0.5-mu greenhouse used 1.5-2 tons of clean coal, saving more than 50% of the coal from the cannonball oven. 3, hot stove is a mandatory heating device. After the fire is energized, the temperature of the furnace wall is greater than 70°C and the fan starts to operate. When the temperature of the furnace wall is less than 70°C, the fan is automatically de-energized. Normal winter nights at 12:00 and early morning 6:00 require two more fires, which greatly reduces the labor intensity of farmers.
