During the operation of boilers and industrial production lines, the generation of smoke, dust, soot, and harmful gases (SOx, NOx, CO) is unavoidable. Currently, strict compliance with National Technical Regulations on the environment is not only a legal obligation to avoid heavy fines, but also a testament to corporate social responsibility and sustainable development.

As a leading expert in the field of boiler manufacturing, HONG NHUT REFRIGERATION & THERMAL CO., LTD. thoroughly understands the physico-chemical properties of each type of flue gas. From that, we provide turnkey Industrial Flue Gas Treatment System design, manufacturing, and installation services, committed to 100% output meeting standards according to the regulations of the Ministry of Natural Resources and Environment.

Common Problems

Consequences of Inefficient Flue Gas Treatment

Outdated smoke and dust treatment systems or those unsuitable for the fuel burned can bring serious consequences to your factory:

High Legal Risks

Violating environmental regulations leads to heavy fines or suspension of operations by authorities.

Environmental Pollution

Emitting toxic gases and dust seriously affects the health of workers and the surrounding community.

Equipment Damage

Flue gas carrying corrosive chemicals damages ducting systems, exhaust fans, and factory structures.

Reputation Loss

Negatively impacts the brand image and the sustainable development goals of the business.

Don't let flue gas become a bottleneck hindering production

With Hong Nhut, the flue gas treatment system is not just to cope with inspections, but a worthy investment for the sustainable and safe operation of the entire factory.

Applied Technology

Flue Gas Treatment Technologies We Provide

Depending on the boiler capacity, fuel type, and emission standards, our engineers will design a combination of treatment modules to deliver optimal efficiency with the lowest operating costs:

01

Multi-Cyclone Dust Collector

  • An important coarse treatment step, using centrifugal force to collect large dust particles into the hopper.
  • Advantages: Withstands very high temperatures, low cost, effectively handles 70-80% of fly ash.
02

Wet Scrubber & Absorption Tower

  • Spraying an alkaline solution mist (NaOH, Ca(OH)2) to thoroughly neutralize SO2, CO, and NOx gases chemically.
  • Advantages: Captures fine dust well, effectively cools exhaust gas, absolutely prevents fire and explosion.
03

Baghouse Filter

  • Exhaust gas passes through hundreds of heat-resistant fabric filter bags (PTFE, PPS). Features an automatic compressed air pulse cleaning system.
  • Advantages: Filters ultra-fine micrometer dust, efficiency up to 99%. Meets the most stringent environmental standards.
Execution Process

Professional Service Deployment Process

Every flue gas treatment project is carefully calculated, measured, and deployed according to industrial standards:

01
Emission Source Survey
Engineers measure flow rate, temperature, gas pressure and take samples to analyze actual pollutant concentrations.
02
Technology Design
Select and calculate the combination of treatment towers (Cyclone + Wet Scrubber, or Baghouse) ensuring QCVN compliance.
03
Manufacturing & Fabrication
Using excellent anti-corrosion materials such as Stainless Steel 304/316, FRP composite coated steel, heat-resistant Epoxy paint.
04
Construction & Installation
Installing induced draft fans (ID Fan), chimneys, gas ducts, treatment towers, and automation electrical cabinets.
05
Commissioning & Acceptance
Test running the system, inviting an independent environmental monitoring unit to measure, sample, and issue a compliance certificate.
Why Choose Us

Why Choose HONG NHUT's Services?

Understand Boilers – Treat the Root Cause

Unlike purely environmental companies, we have the ability to calibrate boiler combustion chamber parameters to minimize smoke generation right from the source, reducing the scale of the treatment system.

System Synchronization

An "All-in-one" solution from the combustion chamber, air supply, to the treatment tower, ensuring perfect aerodynamic flow, preventing boiler blockage or pressure drops.

100% Legal Commitment

Warranty that outlet emission quality always meets discharge standards, passing the most rigorous inspections by state management agencies.

Durable Over Time

The stringent selection of heat-resistant, chemical-anti-corrosion materials ensures the system has a superior lifespan, providing peace of mind for long-term operation.
