1 Weishaupt dual fuel burners Sizes 30 to 70 Version 1LN (NO X -reduction on gas operation) 1/2003 CA

2 Description Weishaupt burners of sizes 30 to 70 were specially designed and developed for industrial applications. The Monoblock-Burners are characterized with multiple excellent features such as: Big firing range and wide area of applications Stable air fan performance excellent combustion characteristics Burner casing can be swung opened Easy to install, setup and maintenance Air damper closed off during burner stop Oil pump and electric oil heater is standard for heavy oil burners Typical gas side Low NO x flame pattern Control Control of air and fuel is performed according to the fuel type, burner size and requirement: Two and three stage The oil part of the dual fuel burner has a nozzle head with two or three nozzles. The capacity regulation is achieved by opening or closing the oil solenoid valves 2 and 3 with corresponding changes in air amount. Sliding two stage On sliding two stage regulation, the low fire and high fire points are assigned within the control range. The burner slides depending on heat re quirement between both operating points. There is no sudden increase or decrease of supplied fuel amount. Modulating Modulating burners operate according to the heat requirement at any operating point within the control range. Reduced starting capacity The burner starts at ignition position via separated pilot line. This way only a small amount of gas flows into the combustion chamber. After a certain delay time the burner operates in low fire. Controlled shutdown from low fire Controlled shutdown of the burner is performed only at low fire. Sudden pressure surge in the gas supply line can be avoided. Gas train As standard, Weishaupt gas and dual fuel burners are always equipped with two main gas valves. Gas train can be built according to most applicable North American codes and standards. Digital combustion manager W-FM100 and W-FM200 combustion manager control all essential burner functions, e.g. fuel and air supply and monitor the flame with digital precision. The target is optimization of operating conditions, maximization of economical aspect and minimizing the emissions. Thanks to the digital combustion technology, such optimization is available today at reasonable cost. Expenses for installation and maintenance are even clearly lower than with conventional technologies. For example, a separate remote panel is no longer required for burner control. Furthermore, remote operation, remote diagnostic and remote monitoring of the appliances are now realizable. This increases the safety and comfort for operator. Applications The burners can be used with heat exchanger such as heating boiler, steam boiler, air heater and for certain process applications. Due to the fact that the burner is capable of overcoming high combustion chamber pressure, they are most compatible with modern high performance boilers. Fuels Oil section (#2 oil), viscosity 6mm 2 /s at 68F (20 C) Gas section Natural gas Propane (LPG) Installation location The burners are designed for indoor operation with temperature of 5F ( 15 C) up to 100F (+40 C) and relative humidity of max. 80% Certification The burners are in compliance with most applicable European and North American standards Excellent service Weishaupt has a high density sales and service network all over the world. The customer service is available every day around the clock. Optimum in house training conditions ensure high quality of service personnel. 2

4 The advantages of digital combustion management Control and Display Unit Digital combustion management means optimum combustion figures, continuous repeatability of setting values and ease of use. Weishaupt burners are equipped with electronic ratio controller and digital combustion management to satisfy the requirements of modern combustion technology, which demand a precise and continuously reproducible supply of fuel and combustion air. Only in this way optimal combustion figures can be ensured over extended periods of time. If required, the burners can also be equipped with O 2 trim* and variable speed control. Error free operation via AZL display and control unit Setting and control of the burner functions is achieved using a control and display unit, the AZL, which is equipped with an LCD display. The AZL is connected to the combustion manager via a safety bus system and can be positioned anywhere according to the user s preferences within 325 ft. (100 m) distance from the burner. Flexible communication possibilities The integrated communication interface enables all necessary information and functions to be transmitted to a BMS system. If required, remote operation and remote diagnosis functions, which are accessible via modem, can be installed (e.g. oil/gas change-over, adjustment of setting values). Communication with external systems via BUS If data has to be exchanged between burners and other heating systems with PLC devices, the information can be accessible via ebus or MODBUS communication system. Integration with building management For control and management functions, Weishaupt offers ProGraf NT - a software product that provides a real time solution to meet all requirements. The price advantage of the new technology With improved technology and ease of use, combustion plant is becoming even more economical than ever before. No additional burner controls are required, since this function is already governed by the combustion manager. Fuses and burner motor starter are the only additional items required. Less installation work means less errors: the burners are tested as a complete unit at the factory. If required, the W-FM 100 is available with an integrated modulating controller and variable speed module. No separate equipment is required. The modulating controller and variable speed module are included as standard with the W-FM 200. Commissioning and service work takes less time. The initial presetting of the burner is carried out at the factory. On site, only the site specific operating points have to be adjusted. To facilitate O 2 trim, only an O 2 probe and O 2 module have to be installed and connected with the W-FM 200 via the internal safety BUS. * In conjunction with W-FM 200 combustion manager 4

6 Proven quality in detail Increased safety via shut off assembly with solenoid valve The electromagnetically actuated safety shut off device isolates the oil supply and return on burner models RGL40 to 70 when the burner shuts down. Oil shut off directly at the nozzle ensures a drip free burner shut down. (Burner model RGL30 uses a system without nozzle shut off). Considerable noise reduction due to sound absorbing air inlet By utilizing sound absorbing materials on the fan suction side it has been possible to reduce operational noise considerably. Cut-away of a nozzle shut of assembly Cut-away of the fan housing Emission figures for 1LN version Excellent emission results are achievable depending on the geometry of the combustion chamber, volume load and firing system (3 pass or reverse flame). [ppm] Example for Natural Gas operation NO x limit* with medium temperature < 230F (110 C) When stating information relating to guaranteed values, certain conditions for measurement and evaluation must be taken into account, such as combustion chamber loading, test tolerances, temperature, pressure, humidity. The designation 1LN is used on the new Weishaupt Low NO x burner series NO x CO * According to German TA-Luft regulation 6
