摘要： In a premixing apparatus that mixes a fuel gas with air, supplies an air-fuel mixture to a burner through a fan, and carries out a control that regulates an opening degree of a variable throttle valve, which is interposed in a gas supply passage, so that an excess air ratio of an air-fuel mixture becomes an appropriate value, in a case where a detected excess air ratio deviates to one side, e.g., a large side, from an acceptable range, a motor is repeatedly caused to rotate by a unit-angle in an opening-degree increasing direction until the detected excess air ratio becomes an appropriate value. In a case where the detected air ratio deviates to the other side, e.g., a small side, from the acceptable range, the motor is caused to rotate, at a high speed in an opening-degree decreasing direction, till a first position that is anticipated that the excess air ratio will become a value that deviates by a fixed quantity from the acceptable range to a large side, thereafter, the motor is caused to rotate, at the high speed in an opening-degree increasing direction, till a second position that is a short of a target position, and subsequently, the motor is caused to rotate by the unit-angle in the opening-increasing direction.

摘要： A gas burner includes a burner body that defines a fuel chamber and a plurality of flame ports. The plurality of flame ports are configured for directing a flow of fuel and air out of the fuel chamber. The plurality of flame ports are distributed along a circumferential direction on the burner body such that the plurality of flame ports are uniformly spaced from a center of the fuel chamber along a radial direction. The plurality of flame ports may be oriented to direct flames away from a void within the plurality of flame ports.

摘要： A insert for a staged fuel burner and processes for using a burner with the insert. The insert has a burner tip that injects a mixture of primary fuel and combustion air into a combustion zone to produce a flame. A staged fuel is also injected into the combustion zone. Prior to being injected into the combustion zone, from the burner tip, the staged fuel, is injected into the burner tip and draws combustion air from the mixer of the burner insert into the burner tip with the staged fuel.

摘要： An innovative oxyhydrogen (HHO) burner system including one or more burner systems is provided to eliminate emissions through total combustion. Each burner system includes at least one HHO gas supply and an external natural gas supply, both of which are connected to a gas mixer. A controller regulates the amounts of incoming HHO gas and the natural gas through being mixed. The mixed gas is supplied to each burner assembly with a predetermined pressure and flowrate to generate a flame for the total combustion of the exhaust stream inside the exhaust pipe. With feedback from an exhaust measuring system inside the exhaust pipe adjacent the outlet, the controller can adjust the burner system for optimal operations and achieve total combustion. Thus, by passing the exhaust or gases through a substantial cross-section covered by each flame, emissions can be greatly reduced or eliminated.

摘要： The present application provides a temperature control device for fluids, which comprises a furnace, a fluid pipe, a plurality of regenerative members, a burner, and an air control device. The burner heats the furnace to store heat to the regenerative members inside the furnace and conduct the thermal energy to the fluid pipe. The fluid pipi outputs a heated liquid. In addition, the regenerative members further produce and transport heated air to the air control device. The air control device converts the heated air to output cooled air.
