recycles the captive working gas by cooling and compressing it, then reheating it again to expand and drive the pistons which, in turn, drive a generator and produce electricity [37]. Figure 19. STM 4-Piston Stirling engine. Source: [38]. STM's 4- Piston engine (Figure 19) relies on a single piston per cylinder design. Each of the pistons in the four-cylinder engine is double-acting, providing both displacement and power. The upper portion of the piston receives the heat from the external combustion process, which increases the pressure of the working gas. By releasing the volume, the gas expands, moving the piston. As the gas expands, it is cooled in the lower portion of the piston, facilitating compression of the working gas and completing the cycle. The STM 4- Piston engine operates at heater head temperatures of 700 – 800 ̊C, with a water/glycol cooling medium temperature of 50 – 70 ̊C, resulting in a net electrical efficiency of almost 30 % [39]. Stirling engine burners have a high tolerance for siloxanes and other particulates, so gas pretreatment may not be necessary. Sterling engine can be operated in the CHP mode (but only hot water), in which waste heat produced as a byproduct of the electrical generation process is recovered and utilized. In STM engine heat is removed from the engine's combustion process using a water cooling system. 66PDF Image | Landfill Gas Energy Technologies
