INLET TECHNICAL PARAMETERS
Main fuel liquid light, medium and heavy fuel oil, naphtha, combustible refinery plant products
Main fuel gaseous natural gas, coal gas, degazační, coke oven and blast furnace gas, biogas, waste gases
Combustion air temperature 20 – 300°C, overpressure against combustion chamber with nominal output 1,6 – 2,5 kPa, quantity in dependency on the burner output and type of fuel
Ignition fuel gaseous stage PB resp. natural gas with pressure 50 – 80 kPa, coal gas resp. coke oven gas with pressure min. 4 kPa, quantity max. 15 Nm3/hour -short term
Press. control air clean, dry, with overpressure 0,6 MPa, quantity max. 2 Nm3/hour - short period
Electric power protected supply 3f 400/230V, 50 Hz for electric motors, 1f 230V, 50 Hz for control members of burner. UPS in case of the requirement of the maintaining of operation in short-term outage of electric power. Inputs per output and design of burner and fuel parameters.
Spraying steam only for oil burners with steam spraying, overpressure 0,6 – 1,2 MPa, slightly superheated
Steam for heating of liquid fuel to viscosity needed for optimal spraying
OUTLET TECHNICAL PARAMETERS
Heat output per assignment in the scope 4 – 80 MW. Burners are delivered in design with automatic control, where the output is controlled on the basis of the evaluation of demanded quantities, for example steam pressure, water temperature etc. Control of the rate of fuel and air is guaranteed by mechanical or electronic link.
Output control range 25 – 100% for burners gas and oil with steam spraying, 33 – 100% for oil burners with pressure spraying
Current air excess 1,05 for burner nominal output
