Refractory Lined Cyclone Separator for CFB Boiler
Product Overview
The refractory lined cyclone separator for CFB (circulating fluidized bed) boiler is a robust, high‑temperature particulate removal unit designed to operate continuously under the demanding conditions of modern coal‑fired and biomass‑fired CFB plants. By integrating a durable refractory lining directly into the cyclone body, the separator withstands abrasive fly‑ash, high‑velocity gas streams, and temperatures often exceeding 900 °C without loss of efficiency. Engineered for seamless integration into boiler ductwork, it delivers stable pressure drop, low maintenance, and a long service life—key criteria for plant operators seeking maximum uptime and compliance with emission regulations.
How It Works
Inside the cyclone, the hot flue gas enters tangentially, creating a vortex that forces heavier particles toward the outer wall. The refractory coating protects the steel shell from thermal shock and abrasion, while the spiral flow drives the particles to the collection hopper at the base. Clean gas exits through the central outlet, ready for downstream heat recovery or emissions control. The design eliminates the need for external liners or frequent replacement, reducing both capital and operational expenditures.

Competitive Advantages
- Integrated refractory lining eliminates secondary liner procurement and reduces installation time by up to 30 %.
- Designed for continuous operation at 950 °C, meeting the most stringent CFB boiler temperature profiles.
- High dust‑capture efficiency (>99.5 %) ensures compliance with local particulate emission limits.
- Modular inlet/outlet connections compatible with standard ANSI/ASME flange sizes for rapid field retro‑fit.
- Low pressure drop (≤0.12 kPa) helps maintain overall plant thermal efficiency.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom refractory lined cyclone separator for CFB boiler?
We accept orders starting from a single unit for prototype or pilot‑plant projects. Larger volumes benefit from tiered pricing and reduced lead‑time.
Can the refractory material be selected based on my fuel’s abrasiveness?
Yes. Options include high‑alumina, magnesite, or low‑coke‑content refractories. Our engineering team will recommend the optimal composition after reviewing your ash chemistry.
What is the typical lead time from order to delivery?
Standard production runs require 15–45 days, depending on size and custom coating specifications. Expedited tooling can shorten the schedule for urgent projects.
Do you provide warranty or after‑sale technical support?
All units carry a 12‑month warranty covering material defects and manufacturing errors. Our technical service team offers on‑site assistance, performance testing, and spare‑part logistics throughout the warranty period.
