The principle of primary and secondary air regulation in circulating fluidized bed (CFB) boilers is designed to maintain stable operating conditions of the boiler, adjusting the volume and temperature of primary and secondary air to achieve efficient combustion and reduce pollutant emissions. Specific adjustment strategies should be optimized and adjusted based on the boiler design and actual operating conditions.

When a Circulating Fluidized Bed (CFB) boiler encounters a cyclone separator breakdown, it's important to address the issue promptly and effectively to maintain the boiler's efficiency and safety. Here are steps that should be taken:
Immediate Shutdown: First and foremost, shut down the boiler following the standard shutdown procedures. This is crucial to prevent any further damage to the boiler and to ensure safety.
Inspection and Diagnosis: Once the boiler is safely shut down, conduct a thor...
Furnace drying, often also called "oven drying" or "boiler drying-out", is an essential step when commissioning a new circulating fluidized bed (CFB) boiler or after any maintenance that might have introduced moisture into the system. The purpose is to remove moisture, ensure the refractory and insulation materials are dry, and prepare the system for safe ignition and operation.
Here are the general steps involved in furnace drying for a circulating fluidized bed boiler:
Inspection: Be...

When we talk about CFBC in the area of industrial boiler, it usually means the circulating fluidized bed combustion. The circulating fluidized bed (CFB) is a type of fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion.
Thermal oil heaters have the characteristics of low pressure and high temperature. They adopt the special manufacturing technology and are equipped with tailor-made flue gas waste heat recovery systems, so they are energy-efficient with higher thermal efficiency than similar products on the market. They also have a high level of automation.
