Show 3 install the thermal oxidizers near process room with proper size. Since combustion chamber has to provide enough residence time to attain a complete combustion at high temperature, a size reduction of the designed system relies on the capability of heat recovery. In other words, honeycomb ceramic regenerator with abundant surface area is able to lessen the size of the combustion equipment (7-9) in order to meet the industrial demand. In this presentation, a pilot honeycomb ceramic rotary regenerative combustion system was first designed based on an individual test of ceramic honeycomb regenerators, where the exhaust gas was prepared by mix organic vapor with air. Subsequently, the investigation of aromatic-contained exhaust gas destruction were carried out by varying inlet aromatic concentration and heat recovery of regenerators, the result shows heat recovery has an advantage to reduce reaction time occurring in combustion chamber, the experimental are under investigation continuously. Experimental Testing of Honeycomb Regenerators A flow diagram of the regenerators testing unit is shown in Fig.l. As valve Fl. Al and Gl are open, termed as combustion mode, the high temperature combustion exhaust, generated in a furnace by firing LNG, is introduced and then storage heat in the regenerator bed, the exhaust temperature at the inlet (T^) and outlet of the bed are continuously recorded. After a designated cycle of time, the furnace burner is then turned off, and valve A2 and G2 are open, termed as heat recovery mode, cold air is induced through the heated bed to raise up the air temperature, the air at the inlet (T0) and outlet (JAPH) are also recorded simultaneously. The temperature efficiency (cp) , used to be a heat exchange capability index of regenerators, is expressed as Eq. (1) . <p ( % ) = 100% X (TAP„ -TJ - (T^-TJ Eq (1 ) In this presentation, a local made ceramic honeycomb regenerator is used to the test (10), each unit has a size of 150* 150><50mm with 100 mesh, i.e., 3364 square access ( 58x58 ) is composed in each unit. The experiments are carried out in a range of 600 - 1200°C to inspect the |
