Example Embodiment
[0022] Example one
[0023] In this embodiment, pulverized coal with a calorific value of 2500 calories is selected. The following experiments were conducted.
[0024] In the first stage of combustion, the atomized pulverized coal (fineness of 90 mesh) is first sent to the pulverized coal burner through the first blower, and the first blower blows in the mixed gas with a volume content of 60% (air gas volume). A mixed gas of 50% by volume and 50% by volume of water gas) and a mixed gas of 40% air at 250°C. The mixed gas is burned in the combustion chamber. The temperature of the combustion flame measured by the sensor is approximately 900°C. As the combustion process continues, under the continuous blowing action of the first blower, the combustion products of the first stage enter the solid combustion stage. In the solid combustion stage, the second blower blows in the mixed gas (air gas) with a volume content of 20%. A mixture of 50% by volume and 50% by volume of water gas), ...
Example Embodiment
[0031] Example three
[0032] In this embodiment, pulverized coal with a calorific value of 3000 calories is selected. The following experiments were conducted.
[0033] In the first stage of combustion, the atomized pulverized coal (fineness of 100 mesh) is sent to the pulverized coal burner through the first blower, and the first blower blows in the mixed gas with a volume content of 70% (air gas volume). The mixed gas is a mixture of 60% and 40% by volume of water gas) and 30% of air, and the mixed gas is burned in the combustion chamber. The temperature of the combustion flame measured by the sensor is about 920°C. As the combustion process continues, under the continuous blowing action of the first blower, the combustion products of the first stage enter the solid combustion stage. In the solid combustion stage, the second blower blows in a mixed gas (air gas) with a volume content of 15%. The volume ratio is 60%, water gas volume ratio is 40% mixed gas), 10% water vapor an...
