A steam boiler includes a boiler housing. A helical coil for boiling water and superheating the wet steam is disposed within the boiler housing. A burner emits combustion gases which heat a heat emitter which is disposed in the inner space of the helical coil. Combustion gases from the burner enter the internal cavity of the heat emitter and then pass through perforations in the heat emitter before contacting the helical coil. As such, the heat emitter is heated by the combustion gases and serves as a radiant heat source for the helical coil.

A waste heat steam generator for a gas and steam turbine power plant is provided. The generator has economizer, evaporator and superheater heating surfaces which form a flow path and through which a flow medium flows. An overflow line branches off from the flow path and leads to injection valves arranged downstream at a flow side of a superheater heating surface in the flow path. The overflow line permits a brief power increase of a downstream steam turbine without resulting in an excessive loss in efficiency of the steam process. The brief power increase is permitted independently of the type of waste heat steam generator. The branch location of the overflow line is arranged upstream of an evaporator heating surface at the flow medium side and downstream of an economizer heating surface.

A control method for boiler outlet temperatures includes predictive control of SH and RH desuperheater systems. The control method also includes control and optimization of steam generation conditions, for a boiler system, such as burner tilt and intensity, flue-gas recirculation, boiler fouling, and other conditions for the boiler. The control method assures a proportional-valve control action in the desuperheater system, that affects the boiler system.

A steam generation system delivers heats water and carbon dioxide at high temperatures in the presence of one or more plasma arc torches and converts the materials into hydrogen and carbon monoxide. The converted gas is delivered to a heat recovery steam generator (“HRSG”) to produce steam, which may be used to power a steam turbine. Depending on the amount of steam and/or power desired, the system may use a control system to vary the flow, temperature and pressure of the gas delivered to the HRSG. The control system may do this by bringing additional torches on-line or off-line in the processing chamber, by adding unheated gas directly from a supply source, shunting the gas from the HRSG, and varying the flow of water delivered to the HRSG.

A steam assisted gravity drainage process that includes the addition of oxygen for recovering hydrocarbons from a hydrocarbon reservoir is described. Steam and an oxygen-containing gas are separately and continuously injected into the hydrocarbon reservoir to heat hydrocarbons and water to drain, by gravity, to a horizontal production well. The process can include controlling the ratio of oxygen and steam from about 0.05 to about 1.00 (v/v). The steam assisted gravity drainage process can further include removing non-condensable combustion gases from the reservoir to avoid undesirable pressures in the reservoir. The non-condensable combustion gases can be removed from the reservoir by at least one separate vent-gas well.

An inline bitumen froth steam heater system including steam injection and static mixing devices is provided. The system heats and de-aerates input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The system is a multistage unit that injects and thoroughly mixes steam with bitumen resulting in output bitumen material having temperature of about 190° F. The system conditions a superheated steam supply to obtain saturated steam at about 300° F. The saturated steam is contacted with bitumen froth flow and mixed in a static mixer stage. The static mixers provide surface area and rotating action that allows the injected steam to condense and transfer its heat to the bitumen froth. The mixing action and increase in temperature of the bitumen froth results in reduction in bitumen viscosity and allows the release of entrapped air from the bitumen froth.
