Design of a Low-Cost Gas Geyser to Reduce CO and CO2 Emissions

Climate change is amongst the most ubiquitous and pressing dilemmas since the late 20th century, demanding utmost attention. In Asia, gas geysers are frequently used by the lower and middle class families for instant water heating. Gas geysers burn fossil fuels that cause harmful and poisonous emissions, risking lives and environment. This paper illustrates a low-cost and innovative gas geyser design that aims to reduce carbon-monoxide and carbon-dioxide emissions. A carbon-monoxide sensor is attached in the heat exchanger of the gas geyser. As a result of incomplete combustion, if carbon-monoxide gas is detected, the gas supply will be modulated to a lower amount, simultaneously increasing oxygen for complete combustion. The exhaust duct is fitted with an activated charcoal filter. Carbon-dioxide and carbon-monoxide can be adsorbed by the filter. Additionally, another carbon-monoxide sensor is placed at the end of the duct. If carbon-monoxide gas is detected there, then the gas geyser will shut down completely.
