摘要： A method for regulating a gas burner, wherein the gas burner has a combustion air supply fan whose rotational speed can be set variably, has the following steps:—operating the fan and detecting a fan rotational speed (nVBL);—changing the fan rotational speed;—measuring an ionization voltage (UION) which correlates with an ionization flow in a flame region of the gas burner;—finding a minimum of a gradient of the measured ionization voltage at the current fan rotational speed;—determining an operating point by measuring the current ionization voltage and storing as an operating point;—while the burner is operating, continuously measuring the current ionization voltage;—determining a deviation between the currently measured ionization voltage and the operating point;—checking whether the deviation (Delta UION) is within a predefined limit (UY) and carrying out a case differentiation: +if the deviation is within the predefined limit (UY), continuing the continuous measurement of the current ionization voltage; +if the deviation is not within the predefined limit (UY), repeating the method from the above change in the fan rotational speed.

摘要： Horizontal immersion tube boilers include a plurality of burner nozzles positioned in substantial alignment with a respective plurality of boiler tubes. Fuel-air mixture directed through the burner nozzles are ignited by a pilot flame system positioned proximate to the burner nozzles within a combustion chamber. The burner nozzles and pilot flame system receive air from a secondary air manifold having inlets that provide secondary air into the combustion chamber. The flames extending from the burner nozzles are directed into the respective boiler tubes, which exchange heat from the flame into water within a boiler shell. The secondary air inlets direct air around the burner nozzles and toward the boiler tubes, creating an air blanket around each burner nozzle for reducing turbulence and guide the flames into their respective boiler tubes. An improved flame arrestor within the nozzle prevents flame back-flow when modulating to lower firing rates.

摘要： A condensation trap comprising an inlet chamber, a vent chamber and an outlet chamber. The inlet chamber is configured to receive condensate fluid through an external opening therein. The vent chamber is in fluid communication with the inlet chamber via a first passageway that includes an internal opening of the inlet chamber. The internal opening is located substantially at an opposite end of the vent chamber as the external opening. The outlet chamber is in fluid communication with the vent chamber via a second passageway that includes an internal opening in a sidewall of the vent chamber and an interior opening in an end of the outlet chamber. The outlet chamber is configured to transmit the condensate fluid through an exterior opening located at an opposite end of the outlet chamber. A vent volume portion is greater than a total volume of an internal space of the inlet chamber.

摘要： A burner and a tile for producing a flame in a furnace. The burner includes a pre-mixer with a venturi that mixes fuel with a first portion of combustion air. The mixture of the fuel and combustion air is passed through the tile. The tile also passes additional portions of combustion air there through. The tile includes flow channels for passing the gases so that it is the tip of the burner. The tile may include a wall to form a staged fuel tile with flow channels splitting the mixture of fuel and combustion air so that some exits the tile inside of the wall, and some exits the tile outside of the wall. The tile may be two pieces. Also a process for improving a flame produced by such a burner and with a tile.
