Abstract

Un dispositivo y un método para prevenir la combustion incompleta en un calentador de agua alimentado a gas cuando el intercambiador de calor seobstruye ya sea en el arranque o en estado de régimen permanente. Un controlador dequemado r aplica un voltaje a una varilla de llama que estáposicionada en la llama producida por un puerto de llama de unquemador bajo condiciones normales de combustion. El controlador de quemador cierra unaválvula de gas selenoide para elsuministro de gas combustible al quemador si la corriente de llama detectada en la varilla de llama está en, o debajo de, unvalor testigo predeterminado. Se dispone de un tubo de reflujo sobre una falta interior. El tubo de reflujo tiene unaabertura conectada en su extremosuperior a una cámara de combustion debajo del intercambiador de calor y lleva también en su porcion inferior un tubo de retorno que tiene una aberturaenfrentando al puerto de llama ubicado debajo de la varilla dellama. El cont rolador de quemador mantiene la válvula de gas solenoide abierta por unintervalo predeterminado requerido por la intensidad de llama para recuperar el valor testigo predeterminado después de que la intensidad de llama sereducepor un aumento de llama temporario siguiendo a la ignicion, cuando la proporcion de obstruccion de seccion transversal en la ignicion no essuficientemente alta como para perturbar la operacion normal del calentador.A device and method to prevent incomplete combustion in a gas fired water heater when the heat exchanger is clogged either at startup or in steady state. A burned-out controller r applies a voltage to a flame rod that is positioned in the flame produced by a flame port of a burner under normal combustion conditions. The burner controller closes a solenoid gas valve for supplying fuel gas to the burner if the detected flame current on the flame rod is at or below a predetermined tell-tale value. A reflux tube is available over an interior fault. The reflux tube has an opening connected at its upper end to a combustion chamber below the heat exchanger and also has a return tube at its bottom portion that has an opening facing the flame port located below the flame rod. The burner controller maintains the gas solenoid valve open for a predetermined interval required by the flame intensity to regain the predetermined witness value after the flame intensity is reduced by a temporary increase in flame following ignition, when the rate of obstruction Ignition cross section is not high enough to disrupt normal heater operation.
