摘要： A system to reduce standby losses in a hot water heater is presented. The system utilizes a dual safety relay valve between the combination gas controller and the burner. The dual safety relay valve bypasses gas to a rotary damper actuator valve to position a damper flapper valve located over/inside the flue pipe. Once the flapper valve has opened to ensure combustion, the gas is allowed to flow back to the dual safety relay valve. Some of the bypass gas may be diverted to boost the pilot or to supply a booster. The dual safety relay valve is then opened to allow the gas supply to the burner. Once the burner is turned off, bypass gas bleeds out of the rotary damper actuator valve to close the damper flapper valve to reduce standby losses through the flue pipe, and to allow the dual safety relay valve to close tightly.

摘要： The present invention relates to a dual venturi for a combustor and, specifically, to a dual venturi for a combustor, which adjusts the amount of gas and air supplied to a burner of a hot water heater and has a motor combined with a damper in order to increase a turn-down ratio (TDR), such that the damper is rotated by the driving of the motor so as to simultaneously open or close secondary air and gas inlets, thereby enabling efficient heating control. The present invention has a separate opening/closing means which is capable of controlling, in two stages, the amount of air and gas flowing into the combustor such as the hot water heater, wherein the opening/closing means comprises the motor and the damper, and the damper is rotated by the driving of the motor so as to simultaneously open or close the secondary air and gas inlets, thereby enabling the control of the amount of air and gas.

摘要： A combustion apparatus having: an upstream-side air supply chamber and a downstream-side mixing passage, both being respectively interposed between a fan and a burner; and a zero governor which is interposed in a gas supply passage and which adjusts a secondary gas pressure to a pressure equivalent to an internal pressure in the air supply chamber, thereby enabling to maximize a turndown ratio to the extent possible. The combustion apparatus has: first and second, totally two, mixing passages; a first gas outlet which is in communication with a narrowed part of the first mixing passage; a second gas outlet which is in communication with a narrowed part of the second mixing passage; a first air valve which varies an opening degree of an air inlet of the first mixing passage; a second air valve which varies an opening degree of an air inlet of the second mixing passage; and a gas valve.

摘要： A damper control system having energy efficient mechanisms. The system may use a heat-to-electric power converter such as a thermopile. Heat may come from a pilot light used for igniting a flame for an appliance. The system may store electric energy in a storage module which could be a sufficiently large capacitor. The system may monitor the position of a damper in a vent or the like and provide start and stop movements of the damper using minimal energy. One way that the system may control electrical energy to a damper motor or another electrical mover of the damper is to use pulse width modulated signals.

摘要： An improved apparatus for on-line coal flow control in vertical spindle mills comprising a plurality of independently adjustable flow control elements and positioning rods that adjust the positioning of those flow control elements. Each flow control element is positioned within the discharge turret of the vertical spindle mill along the outer wall of the discharge turret proximate the entrance to its corresponding coal outlet pipe. The adjustable rods are seated on the side or top of the discharge turret of the coal pulverizer and are connected to the flow control element horizontally or vertically as the case may be. The flow control elements can be independently rotated by +/−90 degrees about the positioning rod axis, moved back and forth in the horizontal plane, and can also be moved up and down in the vertical plane. Therefore, each flow control element has three degrees-of-freedom: one rotational and two linear displacements. The apparatus improves boiler performance by making it possible to operate the boiler with reduced pollutant levels (e.g. NOx, CO) and increased combustion efficiency. Automated computer control of the control surfaces is contemplated.
