Product Overview

The Siemens LMV27 Burner Combustion Manager for Gas & Oil Industrial Burners is an advanced microprocessor-controlled burner management system designed for the automatic control, supervision, and optimization of forced-draft industrial burners. It integrates burner safety control with electronic air-fuel ratio control, enabling precise combustion management and improved burner efficiency.

The LMV27 system manages the full burner sequence including pre-purge, ignition, flame supervision, actuator positioning, fuel valve control, and safety shutdown. Unlike traditional linkage systems, it uses electronic ratio control, allowing accurate adjustment of fuel and air flow across the entire burner load range.

The controller supports single-fuel burners operating in intermittent mode, with up to two actuators controlling air and fuel dampers, making it suitable for industrial burners requiring precise combustion regulation. It also features integrated gas valve proving for leak testing, improving operational safety in gas firing systems.

With advanced diagnostics, digital communication capability, and flexible configuration, the LMV27 series is widely used in industrial boilers, furnaces, and process heating systems where reliable burner automation and efficient combustion control are required.
