The present disclosure relates to systems and methods that are useful for controlling one or more aspects of a power production plant. More particularly, the disclosure relates to power production plants and methods of carrying out a power production method utilizing different fuel chemistries. Combustion of the different fuel mixtures can be controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel chemistries.

Disclosed herein are embodiments of a flare control method and a flare apparatus for automatically controlling, in real-time, the flow of one or more of fuel, steam, and air to a flare. The disclosed embodiments advantageously allow for automated control over a wide spectrum of operating conditions, including emergency operations, and planned operations such as startup and shutdown.

The present invention relates to a method of optimization for continuous combustion systems, which reduces fuel consumption, exhaust emissions and particulate matter. The operating principle is based on the introduction of small amounts of hydrogen in the fuel intake duct of the system, or preferably along the continuous burning chamber, with the aim of optimizing the burning of traditional fuels, improving the parameters of the combustion reaction, the effect of the process in question will increase the temperature of the walls of the chamber, ensuring re-ignition and a more complete combustion and consequently reducing the required fuel flow feed. This optimized combustion will increase the combustion efficiency and reduce its environmental impact.

This disclosure presents a clean burning flare stack, or gas flare, especially the tip portion thereof. The gas flare tip is air assisted to ensure clean burning. The disclosed gas flare tip provides smokeless clean burning of released gases. For example, the gas flare tip burns the released gases in a lean burning condition such that sufficient air is supplied to the surges of gases. In addition, the gas flare tip, by using a low pressure blower mixing chamber, is capable of handling low pressure gases and high pressure gases. As such, different flow rates may be provided to the gas flare tip when different amounts of low pressure and high pressure flammable gases are mixed with sufficient blower air to provide a clean burning condition. The disclosed smokeless gas flare is thus environmentally friendly and aesthetically appealing.

The present invention relates to a hybrid domestic fireplace, configured to burn a fuel mixture of a first combustible fuel and a second combustible fuel, comprising a combustible long chain hydrocarbon fuel, the fireplace comprising: a mixing device, configured to mix the first fuel and the second fuel to form the fuel mixture and, a first fuel supply, configured to supply the first fuel to the mixing device, a second fuel supply, configured to supply the second fuel to the mixing device, and a burner, configured to combust the fuel mixture, wherein the mixing device is further configured to heat the second fuel to a mixing temperature, and wherein the mixing device is configured to mix the first fuel with the heated second fuel to form the fuel mixture.

A burner for burning a hydrogen-containing fuel is equipped with a burner unit which comprises a fuel feed and a feed for a primary oxidant (oxygen) and which is accommodated in a feed for a secondary oxidant (air). A swirl device whose relative position with respect to the burner unit can be altered is provided in the feed for the secondary oxidant. The relative position of the burner unit and the swirl device may be controlled according to a composition of the fuel, in particular according to the water content thereof and the ratio of primary and secondary oxidant. The burner allows flexible adaptation of the burning to fuels of different composition, even during ongoing operation.
