Weishaupt WKG 50/1-B gas burner, DN 40, design ZMH-NR

Fully automatic industrial burner with digital control for efficient gas combustion. The design is adapted for operation with heated air. Rational use of the heat of flue gases in high-temperature boilers minimizes electricity consumption and increases efficiency.

Features burner mod. ZMH-NR:

• combustible fuel: natural (E/ LL), liquefied (B/ P) gas;
• 2-stage power regulation, smooth switching of load level;
• electronic modulation when equipped with an optional regulator;
• possibility of supplying heated air for combustion;
• support for constant and intermittent cycles;
• modified mixing device to reduce NOx emissions compared to the basic design (emission class 2 according to EN 676 standards);
• precisely calculated insulation parameters to reduce temperature and noise levels;
• modular design for increased installation flexibility;
• standard shutdown with low load to prevent sharp pressure drops in the gas pipeline;
• reduced starting power due to an additional ignition device;
• rational arrangement of the main elements for quick access and maintenance;
• full automation of functions, electronic linked control.

Hot air for combustion

Due to the reinforced thermal insulation and a separate fan for cooling the control unit and flame sensor, the burner can be used in high-temperature boilers. The air temperature can reach +250 °C. Recovery of heat from flue gases heated to high temperatures allows an increase in thermal efficiency by 8-9%. A heat exchanger is installed in the chimney to obtain thermal energy.

High accuracy and reliability of control

The Weishaupt WKG 50/1-B, DN 40, mod. ZMH-NR gas burner, art: 27750512 operates under the control of the W-FM100/ 200 electronic combustion manager, which guarantees adherence to set parameters and efficient combustion. The automation unit supports the interconnection of connected devices, monitors leaks, gas and air supply. It reacts to malfunctions by blocking the system.

The linked control system with enhanced interference protection of the CAN bus maintains the fuel-air ratio with digital accuracy.

The W-FM interface provides the ability to connect the burner to a personal computer with appropriate software, the CAN information bus and a centralized control system. Communication via the Internet, telephone or mobile network is available when using a modem.

Communication with the user is carried out using a separate control and indication unit equipped with a display, multilingual indication, and a memory module.

Additional devices

With optional devices, the functions of the W-FM100/200 can be expanded. Installing an O₂ module allows you to monitor the oxygen content in flue gases and adjust the air supply for combustion. When using a frequency converter, the automation unit optimizes the number of revolutions of the fan motor shaft. Oxygen and frequency control modules reduce electricity consumption and increase the efficiency of the combustion system.

Operating conditions

The Weishaupt WKG gas burner is designed for operation in dry closed rooms with a temperature of -15…+40 °C and a humidity of no more than 80%. Installation outdoors and condensation are not allowed.

Advantages of using Weishaupt WKG gas burners

German industrial burners are indispensable for solving a wide range of tasks:

• increasing the level of automation of heating equipment;
• ensuring the reliability and durability of boilers;
• improving the technical and moral level of heat energy facilities;
• reducing emissions of pollutants into the atmosphere with flue gases;
• increasing the level of safety during operation of equipment;
• economical consumption of resources (fuel and electricity);
• expanding control, management and dispatching capabilities.

We can buy a gas burner with a standard, modernized and special mixing unit, emission class 1-3 according to EN 676, for operation with cold and hot air, for conventional and short combustion chambers, in a basic and extended configuration (with optional devices). Individual execution is available upon request.
