Aiming at solving the problems occurred during operation of boiler flue gas denitration urea pyrolysis furnace

this article analyzed the energy consumption

urea decomposition rate and byproducts of the furnace. Moreover

the existing mature urea flue gas pyrolysis technology and urea hydrolysis technology route were compared to find out the optimum technical route for urea pyrolysis reformation. The field operation shows that

by using the urea catalytic hydrolysis technology to reform the urea pyrolysis furnace

the ammonia preparation reliability of the denitration system was greatly improved

the indexes such as energy consumption

urea decomposition rate and the effect on the tail heating surface were obviously optimized

and the investment payback period of the energy-saving renovation was 1 to 2.1 years.
