Wet Scrubber System for Coal Fired Boiler Emissions – High‑Performance Air‑Cleaning Solution
Why Our Solution Leads the Market
When a power plant or industrial facility needs to meet stringent environmental regulations, the wet scrubber system for coal fired boiler emissions is the most reliable line of defense. Engineered for continuous duty, our scrubbers remove acidic gases, particulate matter, and trace heavy metals while maintaining boiler efficiency. Designed for retrofit or new‑build projects, the system integrates seamlessly with existing flue‑gas paths, offering a low‑maintenance, cost‑effective route to compliance.
Core Design Philosophy
Our engineering team follows a “performance‑first” mindset: each component is sized for the worst‑case load, then optimized to reduce water consumption and pressure drop. The result is a scrubber that operates at up to 98 % removal efficiency for SO₂ and 95 % for fine particles, even at the high temperature and humidity levels typical of coal‑fired boiler stacks. The modular layout allows parallel or series configurations, letting you scale capacity without redesign.
How It Works – The Three‑Stage Cleaning Process
- Pre‑Scrubbing Conditioning: A venturi‑type atomizer creates a fine mist of alkaline solution, instantly cooling the flue gas and preparing it for absorption.
- Absorption Zone: Counter‑current contact between the gas stream and the scrubbing liquid maximizes mass transfer, chemically neutralizing SO₂, HCl, and other acidic components.
- Particle Separation & Polishing: A cyclonic separator followed by a high‑efficiency mist eliminator removes entrained droplets and residual solids, delivering clean, dry exhaust to the atmosphere.
Control logic built on PLC technology monitors pH, flow rate, and temperature, automatically adjusting reagent dosing to keep operating costs low while guaranteeing compliance.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for a customized wet scrubber system?
We accept orders from a single modular unit upwards. The MOQ is one fully configured system, which can be sized from 500 Nm³/h to 5,000 Nm³/h based on your project needs.
Can the design be adapted for existing boiler layouts?
Yes. Our engineering team performs a site‑specific CFD analysis and provides a 3‑D integration package that matches the exact dimensions, mounting points, and pipe connections of your current stack.
What is the typical lead time from order to delivery?
Standard lead time ranges from 15 to 45 days, depending on the selected configuration and any special material requests.
Do you offer warranty and after‑sales support?
All units come with a 24‑month full‑parts, full‑service warranty. Our global service network provides remote diagnostics, spare‑part logistics, and on‑site technical visits as required.
