1. Key Technical Specifications of Coal & SZL Biomass fired Boiler

We provide both packaged (DZL) and shop-assembled (SZL Biomass fired Boiler) structures to suit your installation needs. Furthermore, our boilers feature advanced dust collectors to meet local environmental requirements.

The SZL series is a double-drum water tube chain grate steam boiler, ideal for medium to large steam loads and continuous industrial production. Typical industrial sizes range from 4–40 t/h, with strong compatibility for biomass and coal fuels.

The DZL series is a single-drum quick-assembly chain grate steam boiler, widely used for compact boiler rooms and medium-sized factories, commonly covering 2–10 t/h applications.

Both systems are designed for reliable combustion of:

  • biomass pellets
  • rice husk
  • sawdust
  • bagasse
  • wood chips
  • palm shell
  • bituminous coal
  • anthracite
  • mixed solid fuels

The “Small-Flake” Chain Grate – Precision Feeding

  • The Industry Pain Point: Most coal/biomass boilers suffer from “Incomplete Combustion” (black smoke), which wastes 15% of your fuel and clogs your pipes.
  • The Taiguo Solution: Our SZL series features a Small-Flake Chain Grate
  • The Benefit: This precision grate ensures even fuel distribution and zero leakage of unburned particles. Combined with our Variable Frequency Drive (VFD), the grate speed automatically adjusts to the steam load, ensuring every kilogram of rice husk or coal is converted into maximum enthalpy.

Double-Drum SZL Biomass fired Boiler – High-Pressure Stability for Heavy Industry

  • The Technical Edge: For factories requiring high-pressure steam (1.25MPa – 2.5MPa), our SZL Double-Drum Water-Tube design is the gold standard.
  • The Durability Logic: The double-drum structure provides a massive steam-water separation space. This ensures 99% dry steam, protecting your downstream turbines or processing machines from “Water Hammer” damage. It’s built for the 24/7 grueling cycles of palm oil mills and chemical refineries.

2026 Multi-Stage Dust Collection

The biggest fear of coal/biomass owners is the Environmental Audit.


  • The Compliance Shield: We bundle every SZL/DZL system with a Multi-Cyclone Dust Collector or an Electrostatic Precipitator (ESP).

  • The Result: We reduce particulate matter (PM) to meet the strictest 2026 standards of DENR (Philippines) and MOM (Indonesia). You get the savings of solid fuel with the cleanliness of a modern gas plan

Why Factories Choose SZL/DZL to Save 30% Fuel Cost

1) Low-Cost Solid Fuel Replaces Expensive Gas & Diesel

The biggest saving comes from fuel substitution.

Instead of relying on:

  • diesel
  • LNG
  • LPG
  • pipeline gas

Factories can use locally available low-cost fuels such as:

  • rice husk
  • wood waste
  • biomass pellets
  • agricultural residue
  • low-grade coal
  • palm fiber
  • corn cob

For many overseas markets, this can reduce steam production cost by 20–30% or more, depending on local fuel prices.

This is especially valuable for:

  • rice mills
  • textile clusters
  • plywood factories
  • palm oil plants
  • food drying systems

2) Chain Grate Combustion Improves Burnout Rate

Both SZL Biomass fired Boiler and DZL adopt advanced chain grate combustion systems, improving:

  • fuel residence time
  • burnout efficiency
  • air distribution
  • slag discharge
  • ash handling
  • combustion stability

This structure ensures better fuel utilization and less unburned carbon loss.

For biomass fuels with varying moisture, this design is particularly important.


3) Excellent Heat Transfer Efficiency

The SZL Biomass fired Boiler double-drum water tube structure offers:

  • large radiant heating surface
  • membrane water wall
  • stronger circulation
  • higher steam quality
  • faster load response

Industrial models commonly achieve around 86–88%+ thermal efficiency, especially when equipped with economizers and dust collection systems.

The DZL series uses threaded smoke tubes and optimized furnace arches to improve overall heat absorption and reduce exhaust losses.
