TLDR
In this article, a method for starting a firing device, in particular for first-time nonignition of a gas burner, in unknown general conditions, was described, with a characteristic curve of a start air coefficient known from empirical calculations, being stored for the firing device in a memory in conjunction with the burner temperature.
Abstract
The invention relates to a method for starting a firing device, in particular for first-time non-ignition of a gas burner, in unknown general conditions, a characteristic curve of a start air coefficient known from empirical calculations, being stored for the firing device in a memory in conjunction with the burner temperature. According to the invention, a calibration of the start profile is carried out. The ratio of opening of the gas valve (w) to the amount of air ML, required for ignition, is determined in an iterative manner by varying the amount of gas and/or air, and in the event of ignition, the firing device is started and the relevant air coefficient (λ)IGNITION is recorded.

Burner control systems

Roy Bratley
TL;DR: In this article, a gas burner is provided with a thermocouple for sensing the temperature of the surface of the burner, and the signal from the temperature sensor is used to control the air/gas flow by adjusting a variable speed fan and/or a valve controlling the gas flow rates in order to maintain a substantially constant temperature.
