          Technical introduction

            Injection type coal powder burner is a kind of extension device of coal grinding powder spraying machine. At present, it is a kind of most special heating equipment. It adopts special air supply guiding structure with multinozzles which can effectively form trap heat of high temperature. Exchange heat is carried out in radiation vortex method, which changes basically the combustion state of coal powder. It has following features: easy ignition; fast temperature elevation; coal powder will stay in high-temperature section for a long time; high burn-off rate; high thermal efficiency; air output and combustion input can be adjusted according to digital temperature control. it is very convenient to use. It can also eliminate smoke and save energy. By using this equipment, working conditions and environmental pollution can be reduced. The application of this equipment completely avoid the problem of difficult ignition, repeatedly preheating, constant preheating of combustion chamber, uneven coal powder which returns from fire flame dyke and incomplete combustion. Therefore, after using burner, it can save about 20% coal and improve 30% output. 

          Advantages

            Coal powder is a kind of new type kiln heating equipment with advantages such as high utilization efficiency, energy saving and environmental protection. It can be applied to various annealing furnace, metal heating furnace, glowing furnace, precision casting shell furnace, melting furnace, foundry furnace and other relevant furnaces. Coal powder burner has a specially designed multi-class and multi-nozzle air supply guiding structure. It can make coal powder produce high temperature eddy current. It is characterized by high utilization efficiency, dust elimination, energy saving, good working condition and less labor force. As an ideal product for energy saving and environmental protection, it is popular among many customers.
          1. According to aerodynamics, fluidics and combustion mechanism in different conditions such as coal quality, granularity and temperature, it improves the size, air passage and coal passage of combustion chamber reasonably. Coal powder mixes in evenly and burns fully in combustion chamber. The flame injected is characterized by high temperature, strong fire, coal saving and no pollution.
          2. The time used for temperature increase is shortened; the thermal efficiency is high; low request for coal quality; can adapt to wide range of coal; high economic efficiency;
          3. Easy to ignite; temperature can raise very quickly; working efficiency is greatly increased;
          4. Air amount supplied and coal amount assumed can be adjusted by real demand; the temperature of furnace and length of flame can be adjusted in a wide range to meet real need;
          5. The temperature in the burner is very even; the area which is heated is very large; furnace slag will not be stick on the surface work piece; good quality of products;
          6. We have cooperated with many refractory materials factories for practices and tests; the service span is 3 to 6 times of that in similar products;
          7. It can be used for production for constant 24 hours; it is no need to clean everyday; 
           

          Working principle

            Coal powder (under 25 mm) is crushed first; then, coal powder is injected into combustion room of host by metal pipe nozzle and is burnt by oil; meanwhile, blower will send air to combustion room by annular rotating duct at rear cover of host; air will cling to inner wall and rotate for absorbing hot flue gas which will strongly mix and burn with coal powder;  hot flame is injected into drum of dryer for heating dry materials;
