A comfort control system for controlling the comfort level in a building includes a comfort control unit and a remote control unit. The remote control unit communicates with the comfort control unit from a remote location. In one illustrative embodiment, the remote control unit includes a temperature sensor for sensing an ambient air temperature near the remote control unit, and a measure related to the sensed temperature may be communicated to the comfort control unit. A detection block may be included in the remote control unit for detecting when the ambient air temperature sensed by the temperature sensor in the remote control unit is likely to be influenced by a user or other undesirable condition. The comfort control unit may take this into account when controlling the comfort control system of the building.

An aerosol generator includes a fluid supply which supplies fluid to a fluid passage and a heater which heats the fluid into a gaseous state, the fluid passage being located between opposed layers of a laminate. The fluid passage can be a capillary sized passage formed by locating a mandrel between opposed layers of the laminate, bonding the layers together and removing the mandrel such that the space previously occupied by the mandrel forms the fluid passage. The opposed layers of the laminate can be copper sheets and ceramic layers can be provided on the outside of the copper layers. The aerosol generator can be used to generate aerosols containing medicated materials.

A method of and a power plant for generating power by combusting carbonaceous fuel with substantially pure oxygen, and a method of modifying a process of generating power by combusting carbonaceous fuel from combusting the fuel with air to combusting the fuel with substantially pure oxygen. The methods include feeding substantially pure oxygen into a furnace for combusting fuel with the oxygen to produce exhaust gas including mainly carbon dioxide and water, recovering low-grade heat from the exhaust gas by using multiple exhaust gas coolers arranged in a downstream portion of the exhaust gas channel, wherein a first portion of the recovered low-grade heat is used for preheating feedwater; pressurizing a first portion of the exhaust gas in multiple exhaust gas compressors so as to produce liquid carbon dioxide, recycling a second portion of the exhaust gas to the furnace via an exhaust gas recycling channel, using a first portion of steam extracted from a steam turbine system to preheat feedwater, wherein the first portion of the recovered low-grade heat is more than 50% of the total amount of recovered low-grade heat, or larger than the first portion of the recovered low-grade heat in the air-fired process, allowing minimizing of the first portion of the extracted steam, and the expanding of a second portion of the extracted steam in at least one auxiliary steam turbine for driving at least one compressor or at least one pump of the power plant.

The present invention relates to a method of disposing of produced water and to a produced water disposal apparatus including a container for receiving and holding produced water; and a burner having a combustion chamber, wherein at least a portion of the combustion chamber is submerged in the water and the submerged portion of the combustion chamber comprises a sparger tube through which combustion gases emerge into, mix with and agitate the water. The present invention further relates to a mechanism for removing debris from the produced water disposal apparatus. In one embodiment, heat is supplied from an externally operated combustion system, rather than the submerged combustion. In one embodiment, the apparatus provides a concentrator, in which a solute can be removed and recovered from an aqueous medium containing the solute.

A combined cycle power plant (10) has a gas turbine (11), a heat recovery steam generator (16) which is connected downstream to the gas turbine (11) and delivers steam to a steam turbine (19), an exhaust gas recycling line (28) which returns some of the exhaust gases, which flow from the exhaust of the gas turbine (11) through the heat recovery steam generator (16), to the inlet of the gas turbine (11), and also a CO2 separating plant (25) which separates from the non-returned part of the exhaust gases the CO2 which is contained therein and delivers it to a CO2 outlet. A reduction of the equipment cost or a flexible adaptation of the operation can be achieved by a supplementary firing (17) being associated with the heat recovery steam generator (16), which by combusting a carbonaceous fuel produces additional exhaust gases with CO2 content and transmits them through the heat recovery steam generator (16).

The present invention is based on the realization that the carbon dioxide component of industrial gas streams also containing steam can be processed so to utilize either as latent and / or sensible heat the heat available from the steam component to assist in separating carbon dioxide from the remainder of the gas stream. For example, flue gases produced by power stations burning brown coal, black coal or natural gas inherently contain a useful amount of energy that can be harnessed according to the present invention. According to particular preferred forms of the invention, nitrogen and sulphur constituent such as SOx and NOx, H2S and other nitrogen containing compounds may also be removed from the gas stream through direct contact with the absorbing medium and used to produce by-products such as fertilizer material.

A water heating system has a tank, a first heating element, a first temperature sensor, and a controller. The first heating element is mounted on the tank, and the controller is electrically coupled to the first temperature sensor. The controller is configured to detect a stacking condition based on the first temperature sensor and to disable the first heating element in response to detection of the stacking condition.

An inspection vehicle configured to inspect steam generators includes a front chassis having two independently driven magnetic wheels, a rear chassis having two independently driven magnetic wheels, and a connecting member flexibly connecting the front chassis to the rear chassis to permit relative motion between the front chassis and the rear chassis along at least one axis. The connecting member, front chassis, and rear chassis collectively define a receiving area. The inspection vehicle also includes a navigation camera disposed on the front chassis and a pan and tilt inspection camera assembly including a first rotatable arm driven by a first motor, a second rotatable arm disposed on a distal portion of the first rotatable arm, the second rotatable arm being driven by a second motor, and an inspection camera rotatably disposed on a distal portion of the second arm, the inspection camera being driven by a third motor, the camera assembly being dimensioned to be received within the receiving area in a stowed position.

The present invention relates to a method for automatically maintaining the concentration of scale forming minerals in boiler water for boiler systems utilizing bimodal feedwater pumps that deliver a substantially constant feedwater flow to the boiler drum when activated. According to the present invention, the feedwater supply pump and blowdown rate control valve are synchronized to remove boiler water at a predetermined rate when the feedwater pump is activated. The present invention thereby provides a simplified and less expensive method for controlling the concentration of dissolved solids in boiler water despite variations in the steam loads and / or other boiler operation parameters.
