Abstract
Industrial waste heat is one of the most widely distributed and used potential of conventional recyclable energy in industrial production .However, for the low concentration and less energy of low quality waste heat resources, the mature traditional waste heat recovery technology is not suitable for this kind of the recycling of waste heat resources due to its recycling economy and feasibility of the restrictions. In this paper, the secondary utilization of low quality waste heat resources is studied, especially the control system research of low-temperature waste heat recovery power generation equipment by heat pipe waste heat recovery device matching with roots-type steam engine. Control system is managed by system hardware which with C8051F040 single-chip microcomputer as CPU, and fuses the signals of speed encoder and temperature sensor to realize real-time input, and realizes real time communication between touch screen and single chip microcomputer through RS232 bus. By testing, system works stably. Finally it is resulted that the recovery of low-temperature waste heat and the conversion of electric energy can be achieved by the test.
