The modular design of the burners, coupled with their large capacity range, makes them ideally suited to a broad spectrum of special applications. Modular principle Weishaupt WK-series industrial burners are of modular design. That means the fan, pump station, and preheater station are all selected independently of the burner. This concept offers a high degree of flexibility in matching to the most diverse applications. Digital combustion management Digital combustion management ensures the simple and safe operation of combustion plant. Emissions are minimised and economy is maximised. Insulated burner housing The burner housing is fitted with internal insulation (optional extra on the ambientair versions of the WK 40 and 50). This significantly reduces the surface temperature of the housing during operation with preheated combustion air. The insulation also provides effective noise reduction. Heat recovery using preheated combustion air Many industrial processes create high flue-gas temperatures due to the high temperature of the medium used. A 2 heat exchanger in the flue can be used to reclaim a large amount of energy from these hot flue gases, increasing efficiency by up to 10 %. Weishaupt WK-series industrial burners can be operated with preheated combustionair temperatures of up to 250 C. Nozzle-head shut-off device At burner shutdown, or when changing over to gas operation, a safety shut-off device located in the oil atomising system shuts off the oil flow directly in the nozzle orifice, preventing the escape of any oil. Modulating operation Within its operating range, the burner s output is matched to the current heat demand. Reduced capacity at start-up The burners start at gas operation at a reduced ignition load (WK (G) MS > 17.5 MW with an additional pilot burner). This means that only a small quantity of gas flows into the combustion chamber. After the ignition phase, the burner drives to partial load. Controlled shutdown from partial load Controlled shutdown of the burner always takes place from the partial-load position, thus preventing impact on the gas main.

Digital combustion management: recise, simple, and reliable Setting via the control and display unit Digital combustion management means optimal combustion figures, continuously reproducible setpoints, and ease of use. Weishaupt WK-series burners are equipped as standard with electronic compound regulation and digital combustion management. Modern combustion technologies demand a precise and continually reproducible dosing of fuel and combustion air. Simple operation Setting and control of the burner is achieved using a control and display unit. This is linked to the combustion manager via a bus system, enabling the user-friendly setting of the burner. The control and display unit has a clear text display with a choice of languages. An English/Chinese dual-screen version is available as an option should a Chinesecharacter display be desired. Flexible communication options The integrated interface enables all necessary data and functions to be relayed to a master control system via, for example, ebus, Modbus RTU, Modbus TC/I, or rofibus-d. Measures for saving energy and increasing safety and reliability Electronic compound regulation with the W-FM 100 and 200 combustion managers facilitates the extremely precise, hysteresis-free setting of the burner. The burner can be adjusted for ideal combustion figures throughout its entire capacity range. This reduces flue gas losses and saves fuel. Variable speed drive reduces electrical consumption and facilitates a soft start of the combustion air fan. The use of VSD also reduces noise emissions by a considerable amount. O 2 trim saves fuel through a continual and extremely efficient optimisation of the combustion air. Different O 2 probes are available, providing suitable solutions for almost all fuels in applications with flue-gas temperatures below 00 C. Combined CO/O 2 control ensures an ultimate degree of safety. CO emissions are continually monitored and, if the defined limit is exceeded, the burner is operated with an increased amount of excess air for a short period of time before the O 2 trim returns the burner to its preset O 2 setpoint. Should external influences prevent a non-critical condition from being reached, then the burner will undergo a controlled shutdown.

Emissions reduced by the multiflam principle Weishaupt s multiflam technology was designed for gas and dual-fuel burners. By using a patented LN mixing head, NO x emissions on WKseries burners can be reduced to extremely low levels. Weishaupt has set an all-new benchmark, achieving levels below 80 mg/m on gas and 120 mg/m on oil, subject to the combustion chamber geometry. Weishaupt s multiflam burners meet the world s toughest standards. In those countries with particularly stringent environmental legislation, such as Switzerland, multiflam industrial burners are market-sector leaders. Typical flame formation At the heart of Weishaupt s multiflam technology is a special mixing-assembly design which distributes the fuel among primary and secondary nozzles. This results in extremely efficient combustion thanks to recirculation of the flue gases directly at the mixing assembly. mg/m 200 190 180 170 mg/m 200 190 180 170 TA Luft (Germany) 1.

Flame monitoring for demanding safety requirements Testing and optimisation using a software tool Weishaupt Flame Control (W-FC) is a reliable flame monitoring system designed for demanding safety requirements. W-FC 4.0 is for plant with multiple burners firing from the same direction into a single combustion chamber. The W-FC assembly utilises flame frequency to monitor each flame separately via a load-independent on and off threshold for each fuel. The CFC... flame sensor functions in series with the QRA7 flame sensor on the W-FM 100/200 combustion manager. Note: If a turndown in excess of >1:4 or single-burner operation is required, the higher specification W-FC 5.0 must be selected. burners firing from different directions into a single combustion chamber, and for process plant with various flame sources. The W-FC assembly monitors each flame separately via a loaddependent switching threshold for each fuel. This guarantees a distinct differentiation from extraneous sources. The CFC... flame sensor functions in parallel with the QRA7 flame sensor on the W-FM 200 combustion manager. This convenient, load-dependent setting of the on and off thresholds rests upon the electronic VLoad module, which can be configured using software. W-FC 6.0 is to monitor flame stability on plant with flue-gas recirculation for extreme NO x requirements. With this version, the QRA7 flame sensor monitors the flame while the CFC... controls the flue gas volume based on the stability of the flame to ensure safe operating conditions. In this way, reliability of operation with optimal emissions is achieved under varying conditions. The VLoad module enables a load-dependent switching threshold to be tailored to the operational situation. All versions meet EN 298 continuous operation requirements. W-FC 4.0 For classical parallel firing into a combustion chamber, with a maximum turndown of 4:1 W-FC 5.0 For firing into a combustion chamber from opposing directions, and individual/staged firing of multiple burners W-FC 5.0 For plant with various flame sources, such as waste and biomass incineration, process plant, etc. W-FC 5.0 is for plant with multiple W-FC 6.0 CFC... flame sensor Flame root Combustion zone CFC..

Variants D to F Optimal ignition for high-viscosity liquid fuels on WK(G)MS80, using a high-quality ignition burner This variant facilitates reliable ignition at a considerably reduced rating. An ignition electrode is used to ignite the pilot burner s gas mixture. The pilot burner is then used to ignite the main flame upon fuel release. A typical LG bottle (11/ kg) is adequate for ensuring reliable ignition. For example, an 11 kg LG bottle is sufficient for well over 00 ignitions. Flame monitoring is via a separate ionisation probe, which necessitates the use of a W-FM 200 combustion manager. This reliable solution was developed especially for heavy and special fuel oils with widely varying characteristics. It is also suitable for extreme ignitions, such as cold-starting plant that utilises pre-heated combustion air.
