Weishaupt WKG 50/1-B gas burner, DN 125, design ZMH-NR

High-tech gas burner with digital control and the ability to integrate into centralized systems. Prepared for high-temperature operation, increasing combustion efficiency. Operates in continuous and intermittent mode. Power control range: 450-3600 kW.

Features burner mod. ZMH-NR:

• burning natural (E/ LL), liquefied (B/ R) gas, special types of gas – on request;
• smooth two-stage power control, switching of load level without gas consumption surges;
• electronic flame modulation when installing a power regulator (option);
• adaptation for operation with preheated air, temperature up to +250 °С;
• long-term or repeated short-term (restart after 24 hours) operating mode;
• modified mixing device, reducing pressure losses, vibrations and emissions of nitrogen oxides (class 2 environmental friendliness according to EN 676);
• modular design, main structural parts: housing, fan, control cabinet;
• housing protection against overheating, temperature and sound insulation;
• full automation of control and monitoring functions, electronic linked regulation.

High-temperature design

The burner is adapted for operation with hot air. Due to heat recirculation, the thermal efficiency of the boiler is increased. To obtain and use the thermal energy of flue gases heated to high temperatures, a heat exchanger is installed in the chimney. The increase in efficiency reaches about +8-9%. A separate fan is used to cool the control unit and flame sensor.

Progressive combustion technologies

The Weishaupt WKG 50/1-B, DN 125, mod. ZMH-NR gas burner operates under the control of the W-FM automaton. The electronic unit maintains the connection of connected devices, ensures the execution of software algorithms, and quickly reacts to failures. Supports safe and efficient operation of the combustion system.

The W-FM interface allows embedding the burner into a higher-level control system, connecting to a personal computer (with specialized software), CAN information bus, installing a modem for data transmission via the Internet, telephone or mobile communications.

The electronic linked regulation system is equipped with a noise-protected CAN information bus, which supports stable signal transmission to the air damper and gas throttle servomotors.

Weishaupt WKG series

Weishaupt WKG gas burners for heating boilers are widely used to solve various problems:

• increasing the level of automation of boiler equipment;
• reducing the volume of harmful emissions into the atmosphere with flue gases;
• reducing the negative impact on the environment;
• increasing the safety of equipment;
• saving energy resources (fuel and electricity);
• ensuring the reliability of boilers and boiler installations;
• improving the working conditions of service personnel;
• increasing the moral and technical level of heat energy facilities;
• expanding the possibilities of management and dispatching.

The WKG series includes models with a standard, modernized and special mixing unit, 1-3 environmental classes according to EN 676 (mod. ZM, NR, 1LN, LN, 3LN), for operation with cold and preheated (mod. H) air, for conventional and shortened (mod. SF) combustion chambers, for boiler equipment of various capacities.

Options

With the help of optional equipment, you can expand the functionality of the W-FM100/ W-FM200 burner manager and increase the efficiency and environmental friendliness of combustion. For example, when equipped with an oxygen regulation module, a special probe measures the oxygen content in the flue gases. The furnace automaton, after comparing the obtained data with the basic values, adjusts the operation of the air regulation devices, which eliminates excessive rotation of the fan and reduces electricity consumption.

When installing an inverter, the automation unit optimizes the number of revolutions of the fan motor.
