A stove (1) having a combustion chamber (2) supplied by one or more air supply paths (9, 14, 16). One or more valves (11, 15, 17) are provided for controlling airflow through the one or more air supply paths (9, 14, 16). A temperature sensor (4) is used to determine the air temperature associated with the combustion chamber (2), and a flame sensor (3) is used to determine the burn intensity of a fuel in the combustion chamber (2). A controller (5) controls the one or more valves (11, 15, 17) to adjust the airflow through the one or more air supply paths (9, 14, 16) based on inputs from the flame and temperature sensors (3, 4).

A method for continuous firing of combustion chambers with at least three regenerative burners, wherein a first regenerative burner cyclically in the combustion mode conveys supply air and a second regenerative burner in the exhaust mode conveys exhaust air. To avoid escape of hazardous process gases from the combustion chamber into the environment and high carbon monoxide emissions, and to provide energy-efficient firing operation despite use of compact regenerators, the volume flow of the supply or exhaust air through the first or second regenerative burner is reduced continuously and in counter-cycle mode to the volume flow of supply or exhaust air through a third regenerative burner at constant combustion chamber pressure until the first or second regenerative burner is flow-free.

A horticultural smudging system and method for improving the growth and/or production of plants. Combustible material is burnt within a thermal container, and the resulting flue gas containing negative ions and carbon dioxide is propelled onto one or more plants. The smudging system and method may use one or more sensors to detect oxygen, air pressure, and flue gas levels within the thermal container to adjust air intake and the release of flue gas.

A gas turbine engine includes: a combustor that combust the fuel and having an exit, a combustor exit temperature (T40) is the average temperature of flow and a combustor exit pressure (P40) is the total pressure there; a turbine including a rotor having a leading edge and a trailing edge, and wherein a turbine rotor entry temperature (T41) is an average temperature of flow at the leading edge and a turbine rotor entry pressure (P41) is the total pressure there; and a compressor having an exit, wherein a compressor exit temperature (T30) is the average temperature of flow at the exit from the compressor and a compressor exit pressure (P30) is the total pressure there (all at cruise conditions). A method of determining at least one fuel characteristic includes changing a fuel supplied to the engine; and determining a change in a relationship between T30 or P30, T40 and T41, or of P40 and P41, respectively.

A system and method for synchronized oxy-fuel boosting of a regenerative glass melting furnace including first and second sets of regenerative air-fuel burners, a first double-staged oxy-fuel burner mounted in a first wall, and a second double-staged oxy-fuel burner mounted in a second wall, each oxy-fuel burner having a primary oxygen valve to apportion a flow of oxygen between primary oxygen and staged oxygen and a staging mode valve to apportion the flow of staged oxygen between an upper staging port and a lower staging port in the respective burner, and a controller programmed to control the primary oxygen valve and the staging mode valve of each of the first and second oxy-fuel burners to adjust flame characteristics of the first and second oxy-fuel burners depending on the state of operation of the furnace.

A method for burning a fuel in a wood stove having a door to a combustion chamber with a base, which combustion chamber is isolated from the air by an exhaust and an intake at which intake there is provided an air regulator having at least primary, secondary and tertiary air intake ducts. The stove is controlled by a burn controller configured to operate between the different operating, i.e. different combustion states.

The present disclosure addresses systems, media, and methods of configuring a heating system comprising a plurality of combustion-type heating devices fluidly coupled to a vent system. Configuring the heating system includes receiving operating pressure data from one or more pressure sensors in a flue of one of combustion-type heating devices and the vent system. The operating pressure data from the one or more pressure sensors is indicative of a pressure at a corresponding location in the vent system. Configuring the heating system further includes comparing the operating pressure data to stored operational pressure data indicative of operational pressure ranges indicative of permissible operating parameters associated with preventing backflow of flue gases into the one of combustion-type heating devices and outputting instructions for a damper to at least partially open or at least partially close based at least in part on the operating pressure data and the stored operational pressure data.
