As integral components of the boiler system, the selection, design, installation, and operation of boiler auxiliary equipment must comply with a range of technical specifications and safety standards to ensure the overall safe, stable, and efficient operation of the boiler.
Key Technical Specifications
The key technical specifications for the boiler auxiliary equipment are as follows: boiler type-hot water boiler; quantity-3 units; fuel-natural gas; rated power per unit-≥810 kW/h (700,000 kcal/h); rated pressure-atmospheric pressure.
Automatic Control Requirements
The automatic control system requires an instrument/control panel (with an LCD display) that includes a Building Automation (BA) interface and provides the necessary communication protocols. The boilers must utilize fully automatic computer controllers capable of pre-setting operating parameters and automating operational processes to enable unattended operation; these controllers must also feature functions for automatic standby, startup, and combustion load adjustment based on hot water temperature. Furthermore, to enhance energy efficiency and operational flexibility, auxiliary equipment such as fans and water pumps should employ variable-frequency drive (VFD) technology, and Programmable Logic Controllers (PLCs) may be used to manage the linkage and compatibility control among the various auxiliary systems.
