Microcontroller based logic control system for automated novel paddy straw bale combustor technology applied to greenhouse heating

Automation of paddy straw bale combustor technology was achieved by designing a microcontroller based logic control system for controlling feeding, ensuring complete combustion and cleaning the grate removing bottom ash. The generates flue gas at 350 °C to maintain greenhouse air temperature 10 higher (for 24 h continuous operation) than ambient during winter months Ludhiana climate (30.56 °N), India. controls automatic opening furnace door, conveyor speed forward motorized operation chain sprocket mechanism attached door closing specified time, shaker with comber driven 0.5 hp motor actuated operated worm gear.A controlled panel designed six preset values small amount fuel delivery each injector onto combustion. resonant circuit provided help crystal, X1 Mhz C4, C5 capacitors get accurate timing calculations in milliseconds as used circuit. compatible purpose AT89C2051 it matched desired operational parameters low cost. It observed that developed could achieve operations injection >98% efficiency.
