Pulverized coal injection machine :, 1.uniform heating ,special structure, 2.steady fire,high temperature, 3.reduce coke rait - details see: https://www.machineto.com/2013-hot-sale-pulverized-coal-injection-machine-10293851

Application of large capacity Pulverized coal injection :

It can be well used insmall coal fired boiler, reverberatory furnace, annealing furnace and drying furnace,while it grinds the coal and inject the pulverized coal into the combustion furnace at the same time.

Pulverized coal injuection machine includes 3 parts,one is Pulverized coal injection machine,it is used to grind the coal into powder and by the high pressure fan which connect with the pulverized coal injection machine and ,the coal powder after fired, go into the burning room,the burning room will connect with dryer.

Unique Features of large capacity Pulverized coal injection Technology

- Increased burning rate by blending and mixing different types of coals

- Reduced energy and noise by using roller mill

- Energy-saving and anti-explosion by using hot furnace gas as carrying and drying gas

- Primary dust collection by bag-house to eliminate first-stage and second-stage cyclone collectors

- Totally negative pressure environment by using one-stage blower

- Direct blowing technology with blowing and pulverized coal making in the same workshop

- Blowing jars are connected in series and parallel

- Even coal output, pulse-free and wear-resistance of coal conveying pipes by using fluidized vessel and dense-phase transporting

- Pulverized coal is sent to all tuyeres by distributors on the main pipe

- Closed and automatic pulverized coal flow rate control by applying capacitance flow rate meters on main and branch pipes

- Increased pulverized coal burning rate by using oxygen-coal injection lance for partial oxygen enriching

- Oxygen leakage prevention by installing oxygen and safety control system
