CHAENG Calciners are designed as suspension tube calciners to ensure:

• An even distribution of raw meal, fuel and combustion air across
• The entire Preheater System section
• Complete burn-out of the fuel
• Optimum heat transfer between fuel and raw meal
• High calcination rate up to 95 percent

The standard calciner for oil and gas is the Preheater System compact swirl chamber. The Preheater System is the standard calciner for using solid fuels. Both calciners have proved their capabilities of reaching emission limits of worldwide legislation without the use of additives. The reduction of NOx emissions in the Low NOx calciner is based on the principle of “continuous staged combustion” and reaches the “BAT” emission level (best available technology).

Technical Characteristics of the Latest Generation Preheater System:

1. Suitable for production lines of 300 t/d～10000 t/d
2. Suitable for a wide range of raw materials and fuels; the precalciner is uncomplicated in structure and easy to operate.
3. Ready solutions for different fuels, including bituminous coal, anthracite, inferior coal, heavy oil, crude oil and natural gas.
4. Available by-pass solutions for raw meal or fuels with high alkali or chlorine Content
5. NOx-reduction by fractional combustion in the precalciner by up to 50%; up to 70%with SNCR
6. A wide range of solutions for converting daily garbage, industrial wastes, sludge and toxic waste into resources and breaking up toxic materials into their harmless components , thus reducing actual overall pollution
7. Relatively low exhaust gas temperature, low pressure loss and energy consumption; highly efficient cyclone designed f Structural Features: or separating materials and gas.

Structural Features:

High volume calciner providing for high precalcination rate; available calciners in different designs, including curved duct structure, triple-section structure and combined structure

Adaptability to different types of coal, pet coke, heavy oil and natural gas; adaptability to alternative fuels with their specific heat value

Reduced NOx emission by well-designed layout for calciner burners and tertiary air inlets

Cyclones designed for high separation efficiency and low pressure loss

Segmented inner tubes made from new type of heat-resistant cast steel, providing for long service life and easy Maintenance

Fixed splash plates are arc-shaped, which can better distribute materials and increase heat exchange efficiency

Flexible flap valves with good sealing effects, which prevent airflow blockage and facilitate easy maintenance
