The present invention relates to a display device for an artificial fireplace, configured to display a fireplace video that at least comprises flames. The display device comprises a backlight source, which comprises a plurality of LEDs, which are disposed in an LED pattern, wherein the backlight source is configured to emit light with the LEDs, and an LCD-panel, which is configured to selectively transmit and/or modulate light from the backlight source, in order to display the fireplace video. An edge of the LED pattern thereby substantially corresponds to a flame top edge of a flame area in which the flames are imaged in the fireplace video.

A fireplace with a smart glass panel and use of a smart glass panel in a fireplace are provided. The fireplace comprises a heating mechanism, and a smart glass panel positioned proximate to the heating mechanism. The smart glass panel comprising a transparent pane, where at least a portion of the smart glass panel has optic or thermal transmission properties that may be altered between a first state and a second state.

The present disclosure relates to products and methods for modifying the reflection of a light source in a fireplace and other products.

An electric fire apparatus (10)is provided, having an improved simulated fire effect. The electric fire apparatus (10)comprising a bed base (14a)which is at least in part light-transmissible. The electric fire apparatus (10)also has a holographic mesh element (18)as herein before defined which divides the bed base (14a)into a front bed base portion (42a)and a rear bed base portion (42b). At least one light source (50)is provided for directing light through the front and/or rear bed base portions(42a,42b).

A lighting system for an electric fireplace, and a fireplace assembly including such system, may include a plurality of logs arranged in different orientations and in different rows. Some of the logs may include a substantially planar surface facing forwards. A front projector may project a lighting effect onto the logs, including the substantially planar surfaces, and a rear projector may project a lighting effect onto a non-transparent screen positioned behind the plurality of logs. The lighting system desirably provides a realistic three-dimensional flame effect in conjunction with a log set having a natural, split-log appearance. Other features may be included to enhance the lighting system, including internal lights in the logs and in an ember bed, as well as coloration of the logs to enhance the lighting effects and the natural appearance of the logs.

A chemical plant may include one or more fired heaters for heating of process streams. A fired heater may include a direct-fired heat exchanger that uses the hot gases of combustion to raise the temperature of a process fluid feed flowing through tubes positioned within the heater. Fired heaters may deliver feed at a predetermined temperature to the next stage of the reaction process or perform reactions such as thermal cracking. Systems and methods are disclosed to optimize the performance of fired heaters or reduce energy consumption of fired heaters.

The present invention discloses a regulating mechanism regulating the flows from a plurality of gas outlets in a fuel gas valve, comprising an actuator, a push rod, a presser plate assembly, regulating rods and a valve body. Wherein the valve body has a plurality of gas outlets, a regulating rod is provided in each regulating port which exists between the gas inlet and each gas outlet, a resetting device is provided between each regulating rod and the valve body, and the actuator drives the push rod which is around by the regulating ports to move along the axis. The push rod causes the presser plate assembly to move up and down to press or relax the regulating rods and simultaneously change the degree of opening between the head portion of each regulating rod and the corresponding regulating port so that the flow from each gas outlet changes synchronously.

A decorative-flame burner includes a manifold elongated along an axis and a plurality of nipples supported by the manifold. A jet us supported by and protrudes outwardly from each nipple. Each nipple is elongated transverse to the axis from a first end of the nipple to a second end of the nipple. Each nipple has threads at the first end of the nipple and the manifold includes threaded holes spaced from each other along the axis and threadedly engaged with the threads on the first ends of the nipples.

A streamer type flame simulation device includes a casing, some cross-flow fans disposed inside the casing, a first streamer, a second streamer, a supplementary air-supplying device and a light source. The supplementary air-supplying device is arranged in the split joint area between the two cross-flow fans. Since a supplementary air-supplying device is provided between two cross-flow fans for supplying air, the deficiency where air was unable to deliver at the space occupied by the drive motor of the cross-flow fans can be avoided. Various parts of the first streamer and the second streamer can be blown, thus preventing the flame from being cut off and enhancing the overall coordination, which greatly improves the viewing effect of the flame area.

The present invention discloses a regulating mechanism regulating the flows from a plurality of gas outlets in a fuel gas valve, comprising an actuator, a push rod, a presser plate assembly, regulating rods and a valve body. Wherein the valve body has a plurality of gas outlets, a regulating rod is provided in each regulating port which exists between the gas inlet and each gas outlet, a resetting device is provided between each regulating rod and the valve body, and the actuator drives the push rod which is around by the regulating ports to move along the axis. The push rod causes the presser plate assembly to move up and down to press or relax the regulating rods and simultaneously change the degree of opening between the head portion of each regulating rod and the corresponding regulating port so that the flow from each gas outlet changes synchronously.
