1, furnace slagging serious and clean up very inconvenient;
2, the thermal efficiency is too low, coal waste large;
3, pulverized coal combustion is incomplete. Resulted in the recovery powder contains a lot of pulverized coal powder and can not use;
4, the shorter the life and high failure rate of the coal burner, especially crater changed every 15-30 days on the need to seriously affect the normal duration of the user.
Based on the above, our company invite relevant experts to participate in research and develop and cooperate with large refractory plant, have been improved burner from the following aspects.
According to the principle knowledge of and aerodynamics and hydrodynamics of pulverized coal combustion mechanism under different coal, grain size, temperature, concentration, etc., for the spatial dimensions, duct, coal tract structures of the burners were reasonable improvement. Make pulverized coal have a uniform mixing and complete combustion in the combustion chamber, spewing flame temperature is high, fierce fire, economizer, do not pollute the environment and so on.
According to the coal burner's special conditions about boot morning and shut down evening, funded by us, the refractory manufacturers to send someone repeated experiments, successfully developed to adapt to this particular performance conditions firebrick, life is similar products 3 -6 times.
To reduce labor intensity, we will divided the coal burner host into a fixed part and a rotating part, so the maintenance is more convenient. can contact production 24 hours, no daily cleaning residue.
It supporting the use of the range of 25-240 tons of fixed or mobile asphalt mixing plant, pulverized coal per ton of coal asphalt about the amount of 10-12kg, fuel pellets fuel consumption per ton of asphalt around 7kg, if the oil instead coal powder, will significantly reduce production costs, economic benefits will be significantly improved.
The Coal dust burner picture as follow:
