Abstract: The present disclosure provides methods and systems for modulating a solid-fuel-based combustion process. A current instantaneous heat release for a solid-fuel-based heat generator is determined at a virtual sensor. The current instantaneous heat release is compared to a current firing rate demand. When the current instantaneous heat release does not correspond to the current firing rate demand, an underfire air flow of the heat generator is adjusted.

Abstract: There is described herein a method and system for dispatching a single steam flow command to multiple control elements by prioritizing control elements and measuring responsiveness and availability of the control elements using feedbacks. The dispatched single steam flow command may then be adjusted as a function of the responsiveness of each control element.

Abstract: The method of generating immediate and thereafter continuous steam is used in a steam generating system comprising a steam accumulator, a steam outlet connected to the steam accumulator, an outlet valve at the steam outlet, and a quick response steam generator unit connected to the steam accumulator. The method comprises the steps of providing latent steam in the steam accumulator, opening the outlet valve to allow latent steam in the steam accumulator to exit through the steam outlet, feeding water to the steam generator unit, heating the water fed to the steam generator unit while the latent steam exits through the steam outlet and, before the latent steam has entirely exited the steam accumulator, generating steam with the steam generator unit to feed the steam accumulator and controlling the steam flow rate through the steam outlet to maintain it at a value which is essentially not greater than the steam flow rate from the steam generator unit to the steam accumulator.
