Catalytic incinerator
The catalytic incinerator is the same as the convection heat exchanger incinerator except that the catalyst is installed in the combustion chamber. Convection heat exchange incinerators are domestic industry titles, and foreign countries call convection heat exchange incinerators. The waste heat recovery system design makes it economical to use within the lower operating limit (LEL) range. The design is simpler than the regenerative incinerator, the device is small and lightweight, and it can be mounted on a pulley to make it portable. The typical design of the incinerator heat recovery system is to install a tube or plate heat exchanger on the exhaust side of the exhaust gas of the combustion chamber. When there is less particulate matter in the exhaust gas, a plate heat exchanger is usually used. 70%; and the heat recovery efficiency of the tube heat exchanger is usually only 40% to 50%. The heat recovery efficiency is the ratio of the actual recovered heat energy to the maximum recoverable heat energy. The heat recovery efficiency = (T preheat temperature-T inlet temperature) / (T combustion temperature-T inlet temperature).
The catalytic incinerator is particularly suitable for treating exhaust gas with high VOCS concentration and fluctuating VOCS (containing volatile organic compounds) concentration in the exhaust gas. When the VOCS concentration in the exhaust gas is not high and the VOCS concentration fluctuates greatly, the combustion process can only be maintained by adding auxiliary fuel. The addition of auxiliary fuel will cause the temperature in the high temperature area of the incinerator to reach or exceed 1537.8 ° C, resulting in an increase in the amount of NOx generated. Due to the direct contact between the heat exchanger and the flame, VOCS spontaneous combustion may occur in the heat exchange area, so the heat exchanger is mostly made of metal. If the incinerator is operated below 760 ° C, it is required that the VOCS has a better turbulent design and a longer residence time in the furnace. When the exhaust gas contains chlorides, there will be Cl2 to generate HCl to cause corrosion. It is necessary to choose corrosion-resistant materials in the design. Although the investment cost increases, it is necessary.
