COMBUSTION PROCESS OPTIMISATION SYSTEM BY MEANS OF DIRECT MEASUREMENTS INSIDE THE FURNACE

摘要

System consisting of a probe or probes (1) and in a variety of openings (2) that allow the accomplishment of direct measurements or characterisations (gas extraction or placing of sensors) in the interior of the furnace (3) of industrial boilers. These local measurements intend to optimise the operation of each burner, allowing the global improvement of the boiler operation. The probes (1) are designed with very narrow transversal sizes, to allow them to pass through the openings (2) carried out on the membranes (4) (typically around 20 mm) which join the water tubes (5), making up the water walls of the boiler, making the mentioned local measurements feasible with no need to undertake substantial modifications in the boiler. Additionally, the subject of this patent is the fully automated version of the described system, that allows the continuous characterisation and optimisation of boiler combustion conditions, as well as its application to any other combustion process.
