Industrial denitrification equipment is used when production exhaust gas contains nitrogen oxides after burning fuel or heating raw material. It is seen in steel, cement, glass, ceramics, chemical, waste treatment, and boiler rooms. The equipment is matched to the furnace outlet, existing duct, fan capacity, and working load. A small kiln may need a compact reagent spray system, while a large furnace may need a reactor, catalyst area, access platform, and more instruments.
Product Parameters

Gas volume, duct size, space limit, foundation condition, and emission target |
Main Applications
Cement and lime kiln tail gas where dust loading is high and cleaning space has to be kept near the reactor.
Steel heating furnace and sintering gas routes where the load changes during production shifts.
Small and medium industrial boilers that need NOx control without rebuilding the full boiler room.
Site Design Details
For retrofit use, industrial denitrification equipment should be checked with the real duct route, platform space, fan margin, ash hopper position, and reagent storage area. This step confirms whether the reactor, spray lance, access door, and control cabinet can be placed without blocking later operation. If the original duct has many elbows or old expansion joints, pressure drop and maintenance space should be calculated before the drawing is fixed.
FAQ
Q: Is one process suitable for every factory?
A: No. Gas temperature, dust, sulfur, working load, and outlet requirement decide whether SNCR, SCR, or a combined route is better.
Q: What should be checked before making drawings?
A: Duct size, furnace load, access space, fan margin, reagent storage position, platform height, and power supply should be checked.
Q: Can it be made for limited space?
A: Yes. industrial denitrification equipment can be divided into modules, but maintenance doors and lifting space should not be removed just to save room.
