Product details
Denitrification equipment is an environmental protection device used to remove nitrogen oxides (NOx) from industrial flue gas. It is mainly used in thermal power plants, boilers, steel mills, cement plants, kilns, etc., with the aim of meeting the national ultra-low emission requirements (NOx ≤ 50mg/m ³).
At present, the mainstream in industry is divided into two categories: SCR denitrification and SNCR denitrification.
1、 SCR denitrification (selective catalytic reduction)
The most mainstream and efficient denitrification technology currently available
● The working principle is to inject ammonia/urea into the flue gas at 300-420 ℃, and under the action of a catalyst, reduce NO ₓ to harmless nitrogen and water.
● Denitrification efficiency: 85% to 95%
● Core equipment
o SCR reactor (with internal catalyst module)
o Ammonia spray grille (AIG)
o Urea/ammonia preparation system
o Soot blower (sound wave/steam)
Advantages: High efficiency, stable compliance with standards, suitable for ultra-low emissions of large units
Disadvantages: Requires catalysts, high investment and operating costs
2、 SNCR denitrification (selective non catalytic reduction)
Simple and low-cost denitrification technology
● The working principle is to directly spray ammonia or urea solution in the high temperature zone of 850-1100 ℃ in the boiler furnace, react with NO ₓ to generate nitrogen and water, without the need for a catalyst.
● Denitrification efficiency: 40% to 60%
● Core equipment
o Urea/ammonia water preparation tank
o Measurement and conveying module
o Furnace high-temperature spray gun
● Advantages: Low investment, small footprint, simple system
● Disadvantages: Low efficiency, greatly affected by furnace temperature
3、 Common supporting systems
1. Reducing agent system: urea to ammonia or liquid ammonia evaporation
2. Spray mixing system: ammonia spray grille, spray gun
3. Reactor: SCR dedicated catalyst module
4. Monitoring and control: NO ₓ online monitoring, ammonia escape monitoring, DCS automatic control
4、 Applicable scenarios
● SCR: Large scale thermal power plants, sintering machines in steel mills, waste incineration, and projects requiring ultra-low emissions
● SNCR: Renovation of small and medium-sized boilers, cement plants, kilns, and old factories
Recommendation Products
We will uphold the spirit of precision engineering, leveraging its profound technical expertise and end-to-end service capabilities as core drivers.
Working principle: Integrating mechanical, hydraulic, electrical, automation and other technologies, the horizontal shaft is driven by an electric motor to rotate, and the eccentric sleeve is driven by gears to rotate, thereby driving the dynamic cone to make circular oscillations, achieving continuous extrusion and crushing of materials. The crushing chamber is optimized in design, and the crushing effect is not affected by liner wear.

Smelting equipment (blast furnace, converter, electric furnace supporting equipment)
Core positioning: The core equipment for coarse crushing of large materials is mainly used at the front end of the crushing production line to crush large raw materials (with a maximum feed particle size of 1200mm) to ≤ 80mm, laying the foundation for subsequent crushing processes. It is an essential front-end equipment for cement and mining production lines. Working principle: Adopting the principle of squeezing and crushing, the large pieces of material falling between the fixed jaw plate and the moving jaw plate are squeezed and crushed through the reciprocating biting motion of the two jaw plates, achieving coarse crushing processing. It is divided into two types: single elbow plate and double elbow plate. The single elbow plate model has higher production capacity and is suitable for high-yield demand scenarios. Core advantages: simple structure, convenient operation, long service life of wear-resistant parts, large crushing ratio, stable output, suitable for high hardness materials (such as limestone and iron ore), low maintenance cost, suitable for various types of production lines from small to large. Adaptation scenarios: coarse crushing of raw materials in cement production lines, coarse crushing in mining, raw material crushing in sand and gravel yards, coarse crushing in construction waste recycling, etc. Corresponding images (high-definition without watermark, available for direct image search): actual photos of the entire jaw crusher, close-up shots of the jaw crusher feed inlet, jaw crusher mining site, and details of the jaw crusher transmission device.
