2 Regulation Dependent on fuel, burner size and requirements, the regulation of air and fuel is by: • Two and three stage Oil burners have a nozzle assemble with two or three nozzles. A change in firing rate is effected by opening and closing of solenoid valves 2 and 3 with the relevant air volume. • Sliding two stage For sliding two stage control, partial and full load are set positions within the regulation range. The burner’s firing rate slides between the two load points, depending on the heat demand. Thus there are no sudden large increases or decreases in the amount of fuel used. • Modulation Modulating burners operate at any point within the regulation range, depending on the heat demand. Fuel / air ratio The controlled mixing of fuel and combustion air varies depending on the size and type of burner: Size 30 Burner types RL and RMS: Pressure side air regulation via a compound regulated control sleeve in the mixing head. Burner types L and MS: Pressure side air regulation via an adjustable control sleeve in the mixing head for capacity adjustment. Sizes 40 to 70 Burner types RL and RMS: Pressure side air regulation via a compound regulated control sleeve in the mixing head. Burner types L and MS: Diffuser disc matched to burner capacity Increased safety via shut off assembly with solenoid valve A type tested safety shut off assembly in the nozzle of R... type burners (except RL30) shuts off the oil flow directly at the nozzle during pre-circulation and when the burner shuts down. Electromagnetic clutch Electromagnetic clutches are available on request at extra cost for RL oil burners with post purge (see Special Equipment). Oil circulation on heavy oil burners Heavy oil burners have oil warmed by the oil preheater circulated through the oil lines. In this way at the point of ignition the oil in the nozzles is at the correct temperature. Precise oil temperature regulation with Weishaupt oil preheaters Heavy oil burners are fitted with oil preheaters which by means of an electronic thermostat keep the temperature and thus the viscosity of the oil at the required, predetermined level. This results in uniform atomisation and combustion quality. Digital combustion management The W-FM 100 and W-FM 200* combustion managers ensure the simple and safe operation of combustion plant. All important functions, such as fuel and air feed or flame monitoring are controlled with digital precision. The aim is the optimisation of operational functions, the maximisation of economy, and the minimisation of emissions. Thanks to digital combustion management such an optimisation is available today at limited cost. The outlay for installation and service is substantially lower than with conventional technologies. For example, a separate control panel for the burner switchgear is no longer necessary. Furthermore, remote operation, diagnosis and monitoring of the plant can be realised. That makes things safer and simpler for the operator. Applications The burners can be used with heat exchangers such as hot water boilers, steam boilers, air heaters, and for certain process applications. As the burners are capable of overcoming high combustion chamber resistances, they are used primarily on modern high rated boilers. Fuels The burners fire, in accordance with DIN 51 603, fuel oils: Light fuel oil (EL) Viscosity 6 mm2/s at 20°C Medium and heavy fuel oil (S) Viscosity up to 50 mm2/s at 100°C Installation sites In standard execution (materials, construction, protection), the burners are suitable for use indoors at temperatures between -15°C and +40°C and with a maximum relative humidity of 80%. Certification The burners have been independently tested and comply with the following European standards and EC directives: • EN 267 • Machinery Directive 98/37/EC • Electromagnetic Compatibility Directive 89/336/EEC • Low Voltage Directive 73/23/EEC • Pressure Vessel Directive 97/23/EC Outstanding service Weishaupt maintains an extensive global sales and service network. Customer service is available every day around the clock. In-house training by Weishaupt ensures the high standard of their service engineers. *Available early 2004 Description Weishaupt industrial burners, sizes 30 to 70, have been especially designed for industrial capacity ranges. The monobloc burners are noteworthy for their large capacity and operational ranges and numerous other interesting details: • Compliance with the most stringent directives and emission limits • Large capacity and operational ranges • Stable fan reference line - good combustion behaviour • Quiet operation • Burner housing can be hinged open • Easy to install, set and service • Automatic air shut off on burner shut down
