Description Process
» For start up of a boiler a burner lance and a ignition
lance is necessary.
» The burner lance is inject the fluid (oil or gas) into the
boiler which is ignite by the ignition lance.
» The ignited burner lance is firing as long the fuel (e.g.
coal, waste) burning in a suitable way.
» The retract process is control by two customized
LINTRA cylinder systems.

Application
» Fluid
» Oil or Gas
» Fuel
» Coal, waste, biomass, etc.
» Function
» Burner lance
» Inject fluid to start up the boiler/fuel
» Case of emergency (power failure): The lance remains in the
current position.
» Feature: spring return (monostabel) solenoid valve.
» Ignition lance
» Electrical ignite of the fluid which is provided by the burner lance.
» Case of emergency (power failure): The lance move back to the
starting position outside the boiler.
» Generally, the lances are only in use for the start up process.
