Sistema de control basado en Arduino para una caldera de biomasa

Biomass is a renewable energy, whose use has been increased in applications such as heating and domestic hot water (DHW). Biomass boilers require ash cleaning and an optimum combustion process for achieving an cient operation. In this work, the design and implementation of a new burner and its automatic control system for a commercial biomass boiler (25 kW) is presented. The main aims of the automatic control system are to reduce emissions, increase efficiency, improve the cleaning system and create a more intuitive monitoring and control panel with for user interface. This control system is based on the open and low cost Arduino platform, so that the user can incorporate future improvements or upgrades in the operating mode. With the developed control system, noteworthy improvements have been achieved in terms of emissions and efficiency.
