Hebei cement denitration equipment - new cement denitrification selective non-catalytic reduction (SNCR) denitration technology, flue gas NOx end processing technology is the reducing agent containing amino group (urea or ammonia) under the premise of not using a catalyst spray evenly the boiler temperature in the 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 device does not require structural reform, short construction period. 3. Basic no adverse effects on equipment and production technology, 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 can be staged combustion low NOx combustion technology or common use. Cement 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, the dissolution process does not require a reducing agent, a high degree of automation. 3, simple operation, low failure rate. 4, have a spare key equipment components to ensure safe operation. 5, low investment and high efficiency. 6, no effect on the cement production process and quality of cement. 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 occurs, eliminate security risks, disable flushing response pipeline overhaul to prevent leakage of ammonia burns people. Cement SNCR (urea) denitration system System type: SNCR-EEN systems: measurement systems, configuration systems, conveyor systems, storage systems, water systems, dilution system, pressurization system, distribution system, fogging system, irrigation system, drainage 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, low investment and high efficiency. 5, non-toxic urea, system safety factor, there is no security risk. 6, no effect on the cement production process and quality of cement. 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. SNCR denitration system by storing the waste system, water storage systems, pressure distribution systems, spray atomization system, automatic control system consisting of five systems; process (with ammonia as an example): ammonia tanker sent mass concentration of 20% - 25% of the ammonia, ammonia pump with discharge or pumped tanker carrying ammonia tank, ammonia storage tank of ammonia for the boiler at least 5-7 days of continuous operation, stable fluid flow in order to protect the nozzle condition variables, the and airbrushed force needs, to meet the needs of fog covered field before ejecting it needs to be certain of diluted ammonia, ammonia from the ammonia tank and water from the water tank after the pump pressure by mixing into the mixing tank of ammonia aqueous solution diluted to a suitable concentration injection, and then sent to the gun through the injection pumping pressurized flow through piping, ammonia after atomizing spray gun to the decomposition temperature of the furnace proper position nitrogen oxide reactions.
