A Design of Control System for Energy Saving and Carbon Reduction

Current development in boiler operation is focused on improving energy efficiency, reducing energy consumption and reducing greenhouse gas emissions. In light of increasing fuel costs and awareness in environmental concerns, improvements in boiler efficiency have been an important issue for achieving the optimization of energy consumption. Performance quantification is the important result of system evaluation and provides a useful index to assess and improve performance and future designs, technologies and applications. This research uses heavy oil to design special combustion optimization methods by using an Oxygen-Hydrogen mixed gas supplemental injection for combustion to provide boilers with improved thermal energy, and tests potential energy saving efficiency, with a targeted result of 15% to 20% savings. The waste gas emitted by boilers, (including HC, CO, CO2, NOx, SOx, etc.), seriously damages the environment and creates a negative impact on air quality. This research measures and investigates changes in emissions of waste gases produced by heavy oil with different Oxygen-Hydrogen mixtures. The results indicate that 1.5 ton steam boiler using heavy oil with an introduction of 7200L/hour of Oxy-Hydrogen will result in reductions of 17.6% to 19.1% in fossil fuel consumption, with the more significant reductions when using heavy oil. Since Oxy-Hydrogen assists in helping to achieve a more complete combustion of fossil fuels, supplementing with Oxy-Hydrogen significantly decreases emissions of CO, hydrocarbons and particle pollutant by 74% and 94% respectively. Thus, the introduction of Oxy-Hydrogen can effectively inhibit soot and other emissions.
