Furnace wall of contaminated soil pyrolysis or incineration furnace

When pyrolysis or incineration treatment is adopted by the soil which is contaminated by organic matter, the smoke is prone to generating a carbon deposit on a furnace wall. The effective volume is reduced, the blockage is also prone to being caused, and the treatment efficiency is affected. The carbon deposit is not conveniently examined, CO2 and O2 sensors are often adopted to estimate the carbon deposit generation degree, the reliability is low, chemicals are mostly adopted to clean the carbon deposit away, and the cleaning process is complex. The invention provides a furnace wall of a contaminated soil pyrolysis or incineration furnace. The structure of the furnace wall can achieve the effects that no chemical exists, and the carbon deposit on the furnace wall is easily and instantly cleaned away; a worker just observes the furnace wall from the exterior or irradiates the furnace wall through lamplight so that the portion with the carbon deposit can be judged; only the portion withthe carbon deposit is cleaned away in a selective mode, and other portions are not involved; and the carbon deposit forming portion is induced.
