Siemens is participating in 2023 China International Heating, Ventilation, Air Conditioning, Bathroom and Comfortable Home Systems Exhibition (China Heating Exhibition) with the theme of “Zero Carbon Pioneer Smart Space”. At the exhibition, Siemens showcased a comprehensive range of innovative digital and low-carbon technologies and solutions in the field of combustion control, including: Industrial combustion control system, combustion management system, combustion equipment controller, general boiler controller, pre-premixed combustion controller and gas valve group, high back pressure and high power post-premixed combustion solutions, and urban intelligent heating monitoring system, etc.

Siemens Industrial Combustion Control Systems is an expert in industrial process heating solutions, providing combustion equipment manufacturers with safe, reliable, energy saving and emission reduction technologies and solutions. It can achieve a wide range of mechanical, electronic and various sensors, and continuous innovation in high efficiency burners, heat recovery, low emission levels and the use of biofuels, and actively introduce sustainable solutions for the future.

The new generation of Siemens LMV62 combustion management system features a full Chinese interface and quick debugging function, making it easier to set up and debug clean combustion applications such as FGR/FIR. AZL66 man-machine interface two buttons one button and multi information post display, so that man-machine interaction more smooth. Moreover, the system can choose a variety of torque actuators (3/10/20/35Nm), configuration of up to 5 actuator combinations, with VSD conversion function, to meet different burner design requirements.

Siemens FIR combustion equipment controller makes combustion control more convenient and flexible. The LME2/3 combustion controller is suitable for the control and monitoring of medium and high power blast burners using oil or gas, electronic proportional regulation mode. The LMV2/3+AZL23 can simultaneously be configured with two 90°/900 step high-precision actuators for real-time control and verification of actuator position, realizing accurate electronic air-fuel ratio control. Dual safety processor design can meet the SIL3 safety level, for the safety of the burner escort. With adjustable timing parameters, variable frequency fan control and PID load control, it can provide flexible configuration solutions for different FIR burners. The Modbus communication feature and optional OCI460 module provide Climatix Cloud Platform services to digitize burners and facilitate service.

Siemens POL468 is a versatile programmable boiler controller that can be used in combination with Siemens LME and LMV series combustion controllers to ensure burner safety while giving full play to its flexibility according to different application requirements. The boiler controller comes with standard applications for hot water boilers, steam generators, and steam boilers for direct selection or personalized extension, and the group control cascading function can connect up to eight units simultaneously, as well as directly to the Siemens Climatix IC cloud service platform for plug and play.

Siemens universal pre-premix combustion controller LME7 is suitable for the control and monitoring of fuel or gas, segment or continuous proportional adjustment mode, medium and high power blast burners. It is based on dual safety processors, and meets the functional safety requirements of international standard IEC61508 for microprocessor based control systems used in boiler and combustion and other dangerous situations. LME7 can use PWM converter fan, built-in valve leak detection program, also can receive PID controller output 3-bit floating-point or analog signal. In addition, the LME7 is a modular combustion controller that combines standardization and flexibility by providing different program modules for different combustion control applications.

Siemens pre-mixed premixed combustion gas valve bank is based on Siemens unique zero pressure hydraulic actuator SKP25.3x and gas valve body combination. Unique pressure sensing design and electro-hydraulic actuator make it durable and reliable, high tolerance, strong anti-interference ability. And its separate modular design, the same implementation of structure selection and selection of different diameters of VGD20/41 series valve body, not only can meet the needs of different power burners, but also easy to carry out on-site installation and maintenance services. The product and performance have been fully verified in the premixed condensing furnace market in China, Europe and the United States.

Siemens gas valve bank for post-mixing premixed combustion is based on Siemens unique differential pressure hydraulic actuator SKP55 and gas valve combination, flexible application in high back pressure steam or hot water boilers. Combined with the unique post-premixed combustion system design, it improves the premixed quality at small load levels, and the adjustment ratio can be up to 6:1. SKP55 pneumatic differential pressure air fuel ratio control, can automatically compensate filter dirty plugging, accurately keep air fuel ratio constant. The valve body of different caliber can realize the power range of 800-4800kW, and can be used with Siemens LME73/LMV37 burner controller, POL468 boiler controller, to form a complete post-premix combustion technology solution.
