Demonstration of CO2 Emission Savings From Biomass Boilers with a 100 kW Wood Fired Boiler

Abstract

An obvious solution to reducing CO₂ emissions is the use of renewable energies. In this article, using domestic temperature data, we show how much CO₂ can be saved compared to a natural gas appliance in an average heating season. In the article, we also discuss the expected fuel consumption each month. From the point of view of environmental protection, the lifetime of the system is also highly important, since the production of devices and system components, construction, and waste management are also associated with the environmental impact. In the case of wood boilers, the greatest risk (premature failure) is the corrosion of the combustion chamber. Condensation occurs in the combustion chamber during cold starts. To avoid condensation, manufacturers require the increase of the return temperature. In the article, we present the properly designed hydronic connection and the step-by-step method of sizing the most typical system element: the control valve. We present the flow conditions associated with the operating conditions of the boiler. Finally, we also present our calculated CO₂ emissions.
