Preheater
新一代預(yù)分解系統(tǒng)技術(shù)特點
●Suitable for production lines of 1, 000 t/d ～ 12, 000 t/d;
●Suitable for a wide range of raw materials and fuels; the precalciner is uncomplicated in structure and easy to operate;
●Targeted solutions for different fuels, including bituminous coal, anthracite, inferior coal, heavy oil, crude oil and natural gas;
●Available by-pass solutions for raw meal or fuels with high alkali or chlorine content;
●NOx-reduction by staged combustion in the precalciner by up to 70%; up to 80% with SNCR;
● A wide range of solutions for converting daily garbage, industrial wastes, sludge and toxic waste into recycling resources, toxic
materials harmless treatment;
●Low exhaust gas temperature, low pressure drop and energy consumption; highly efficient cyclones designed for 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, petcoke, 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 drop;
●Segmented inner tubes made from new type of heat-resistant cast steel, providing 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 short-circuit and facilitate easy maintenance of preheater
