The invention relates to a heat radiation chamber for boilers, consisting of parallel bars which are equidistant from each other, attached to two rings and supported on legs. Said chamber is arranged inside the combustion chamber of boilers. When combustion occurs, the heating of the bars improves the combustion and, as hot air passes between them, the temperature increases.

An acoustic damping device is provided that includes a resonating tube defining a resonating cavity with a predetermined characteristic length and a tube end defining a cavity opening, as well as a case configured to reversibly secure the tube end in fluidic communication with a fluid volume enclosed by a liner. The cavity opening is connected with the resonating cavity. The case includes a vented ferrule adpressed over a perforated region of the liner. The vented ferrule defines a ferrule opening that is aligned with the perforated region of the liner and the cavity opening to form the fluidic communication between the fluid volume and the resonating cavity.

A conduit through which hot combustion gases pass in a gas turbine engine. The conduit includes a wall structure having a central axis and defining an inner volume of the conduit for permitting hot combustion gases to pass through the conduit. The wall structure includes a forward end, an aft end axially spaced from the forward end, the aft end defining a combustion gas outlet for the hot combustion gases passing through the conduit, and a plurality of generally radially outwardly extending protuberances formed in the wall structure. The protuberances each include at least one cooling fluid passage formed therethrough for permitting cooling fluid to enter the inner volume. At least one of the protuberances is shaped so as to cause cooling fluid passing through it to diverge in a circumferential direction as it enters into the inner volume.

The invention concerns a gas turbine combustion system, including a gas turbine. The gas turbine includes at least one compressor, at least one combustion chamber for generating working gas, wherein the combustion chamber connected to receive compressed air from the compressor, at least one turbine connected to receive working gas from the combustion chamber. The combustion chamber consists of an individual can-combustor or comprising a number of can-combustors arranged in an annular can-architecture, wherein the can-combustor having at least one premixed burner. The ignition of the mixture starts at the premixed burner outlet and the flame is stabilized in the region of the premixed burner outlet by means of a backflow zone. The can-combustor comprising a number of premixed burners arranged uniformly or divided at least in two groups within the can-combustor.

Oxy-pyrohydrolysis articles, systems and methods for total halogen, in particular fluorine analysis are provided. A sample containing halogen elements is provided into a pyrotube for combustion. A combustion-enhancing bed including ceramic fibers or fabrics is disposed inside the pyrotube to enhance the combustion and protect the pyrotube from damage by corrosive gases.

A resonant sound absorbing device of a gas turbine combustor includes a plurality of resonance chambers independently disposed side by side in an axial direction of the gas turbine combustor so as to communicate with a gas passage of the gas turbine combustor via acoustic holes. The plurality of resonance chambers include n related resonance chambers each satisfying: $\begin{array}{cc}0.9\times {.Math.}_{i=1}^n\frac{F_i}{n}\le F_i\le 1.1\times {.Math.}_{i=1}^n\frac{F_i}{n}& \left(A\right)\end{array}$
where n is an integer of 2 or more, and Fi is a peak frequency corresponding to a maximum sound absorbing ratio of the ith related resonance chamber of the n related resonance chambers.

A soundproofing device for a transmission according to the present disclosure is provided to transmit the power of one or more prime movers (for example, internal combustion engine and electric motor). The soundproofing device includes a Helmholtz resonator including: a wall that forms a Helmholtz resonance chamber; and an opening formed in the wall so as to cause the Helmholtz resonance chamber to communicate with the outside of the Helmholtz resonance chamber. The wall includes a transmission case that accommodates the transmission and a housing of a component mounted on the transmission (for example, PCU housing). The Helmholtz resonance chamber is formed between the transmission case and the housing.

This disclosure provides an apparatus for a portable thermal power station and related methods. The power station includes a burner, a reservoir, an output power plug, and a thermoelectric generator. The burner produces combustible heat across a surface. The reservoir stores a cooling fluid. The output power plug electrically connects to an external device. The thermoelectric generator receives heat energy, converts the heat energy to electrical energy, outputs the converted electrical energy to the external device, and disperses excess heat energy to the reservoir.
