Denitrification boiler / utility boilers denitration manufacturers selective non-catalytic reduction (SNCR) denitration technology, is the end of the NOx flue gas treatment technology, is the reducing agent containing amino group (urea or ammonia) under the premise of not using a catalyst evenly sprayed into boiler temperature range of 800 ~ 1100 ℃ areas, selective reduction of NOx in the flue gas of N2 and H2O, in order to achieve NOx reduction goals. Usually in conjunction with a low-nitrogen combustion denitration to achieve higher efficiency. SNCR Advantages 1. Low investment cost, without the use of catalysts, low running costs, there is a great economic advantage. 2. The boiler does not require structural reform, short construction period. 3. Basic without adverse effects on the boiler and the production process, without having to adjust the operation of other devices use after transformation. 4. Compared with the SCR does not generate liquid or solid waste. 5. suitable for China's current low-tonnage circulating fluidized bed boiler, the denitration efficiency is about 60% to 85%, and low NOx combustion can or staged combustion technique commonly used. Such as industrial boilers, similar to the power plant boiler incineration plant boilers, waste boilers, glass melting kiln, the flue gas contains large amounts of NOx, the need for flue gas denitrification. Feasibility SNCR denitration follows: ???? 1, SNCR denitration technology is mature, has been widely used at home and abroad of power plant and industrial boilers?. ????? 2, the internal temperature of the boiler has the right window, you can ensure maximum denitration rate. ????? 3, small and medium sized boiler furnace small cross-section, is conducive to the full reaction of the reducing agent. ????? 4, the efficiency is normally issued more than 80%, to meet increasingly stringent environmental requirements. ????? 5, low investment and a basic need to rebuild the boiler, had little impact on the boiler system. Boiler SNCR (ammonia) denitration system System type: SNCR-EEA system consists of: unloading ammonia systems, storage systems, water systems, hybrid systems, pressurized systems, measurement systems, distribution systems, spray systems, irrigation system, sprinkler system, sewerage system, control system. System features: 1, no large-scale transformation, without using a catalyst, does not produce solid waste. 2, simple operation, low failure rate, stop automatic washing, to prevent crystallization of the urea solution in the pipeline. 3, has a spare key equipment components to ensure safe operation. 4, the best reaction temperature boiler temperature SNCR and high efficiency of denitrification. 5, non-toxic urea, system safety factor, there is no security risk. 6, had no effect on the production process and boiler equipment quality. System purposes: for flue cement production lines, power plant boilers, industrial boilers and denitrification. System Maintenance: regular line valves and denitration gun checked, to prevent leaking phenomenon, flushing of the pipeline were shut down to prevent crystallization of the urea solution, clogging lines. Boiler SNCR (urea) denitration system System type: SNCR-EEN systems: measurement systems, configuration systems, conveyor systems, water systems, dilution system, pressurized systems, distribution systems, spray systems, flushing systems, sewage systems, control systems ??; Features: 1, no large-scale transformation, without using a catalyst, does not produce solid waste. ?????? 2, simple operation, low failure rate, stop automatic washing, to prevent crystallization of the urea solution in the pipeline. ?????? 3, has a spare key equipment components to ensure safe operation. ?????? 4, the best reaction temperature boiler temperature SNCR and high efficiency of denitrification. ????? 5, non-toxic urea, system safety factor, there is no security risk. ????? 6, had no effect on the quality of the production process and boiler equipment.
