The utility model relates to a flue gas denitration technical field provides a monitoring system of urea pyrolysis oven deposit, including temperature measuring device, controlling means and alarm device. Wherein, temperature measuring device's point for measuring temperature is arranged on the outer wall of urea pyrolysis oven export / " U " type section entry to acquire the afterbody temperature of urea pyrolysis oven, controlling means and temperature measuring device connect to the analysis is carried out to temperature to the point for measuring temperature, alarm device and controlling means connect to output result according to controlling means selects whether to send alarm signal. This system to the crystallisate that produces in the urea pyrolytic process mainly in pyrolysis oven bottom deposit's the circumstances, install the temperature monitoring device in near urea pyrolysis oven afterbody position, in case pyrolysis oven bottom emergence crystallisate deposit, can be timely, accurate provide warning information to the staff, the staff of being convenient for in time finds and handles the problem of urea pyrolysis oven to avoid the deposit to block up the urea pyrolysis oven, reach the fail safe nature's of improvement urea pyrolysis oven purpose.
