This article presents the modeling and simulation of the sequence of operations of the boiler burner igniters in a gas-fired thermoelectric. The firing of the igniter is one of the steps necessary for the firing of the boiler burners. A kind of hybrid systems called Mixed Logical Dynamics Modeling scheme is proposed to model systems that have linear dynamic equations subject to linear inequalities involving real and integer variables. A simulation are reported and shows the steps and constraints to be met for starts the firing of the igniter.
