In this experiment, we studied the construction of incinerators using Hydrogen gas as fuel in small hospitals. The Hydrogen Gas Incinerating System in this study consists of 3 major parts, the Water Separation System, Furnace and Combustion System, and the DC Power Control System. The authors used water mixed with Sodium Bicarbonate (NaHCO3) solution to separate Hydrogen (H) from water by using 12 VDC and 15.50 A which resulted the 909.09 ml/min of gas flow rate to burn 100 grams of infected waste. The experiment showed that the waste was completely burnt into ash within 13.35 minutes and the average power consumption was 0.04 kW-hr. It was concluded that the gas flow rate should not be less than 800 ml/min because it can have a fire back phenomenon. The result also showed that the burning cost of waste incineration in this study equaled to 1.50 baht/kg which was much cheaper than the one of general infected waste in hospital which costs 5 baht/kg.
