Biomass Fired Boiler

Founded in 1956, Yuanda Boiler is a cartified A-class industrial boiler manufacturer with over 69 years of experience.

We designs and manufactures a complete line of biomass boilers based fuel type, featuring popular models such as DZL, DZH, SZL, SZW.

Compliant with international standards (CE, ASME, EAC, DOSH, GOST, ISO etc.)

Key Features

High fuel flexibility, compatible with a variety of fuels
1. Standard biomass fuels: wood pellet, biomass pellet, rice husks, coconut shells, palm kernel shells, and nut shells...
2. Irregular or high-moisture fuels: wood waste, sawdust, wood chips, shavings, bark, bagasse, forestry residues, palm fiber, EFB, textile waste, and other high-moisture fuel
3. Supports co-firing with coal, adapting to complex fuel scenarios

Combustion systems tailored to fuel characteristics
We have a variety of advanced furnace & grate designs to precisely match different fuel characteristics:
1. Chain grate/traveling: Suitable for uniform pellet fuels, big size fuel
2. Moving/Reciprocating grate (step grate): Supports irregularly shaped fuels and high-ash, high moisture biomass
3. Bubbling Bed Grate : high moisture content and low calorific value fuel

Balance between high performance and low maintenance
1. Combustion efficiency ≥88%: The optimized furnace design and air distribution system ensure complete combustion.
2. Low ash accumulation: The special grate structure and flue design reduce dust accumulation and extend maintenance cycles.

DZL&DZH Boiler

This boiler system incorporates a water-fire tube structure with spirally corrugated furnace tubes and a wing-shaped flue, significantly improving heat transfer efficiency and structural stability. Its newly designed furnace arch enables a reversed "α-shaped" flue gas flow, combined with a secondary air distribution system, ensuring full combustion and reduced emissions.The optimized heating surface layout allows for higher thermal efficiency and lower operating costs

① DZL boler using chain grate, mechanized loading and deslagging, more suitable for wood pellet, briquette fuel, rice husk, palm kernel shell;

② DZH boiler using a manual type traveling grate, manual loading and deslagging, more suitable for firewood, wood blocks, logs, jute and solid waste.

SZL&SZW Boiler

The SZ series boilers utilize a dual-drum arrangement and membrane water-cooled wall structure, equipped with an independent cyclone combustion chamber and secondary air system. They boast a large furnace volume and complete combustion. They offer fast startup, rapid steam production, high thermal efficiency, and low operating costs, and feature a built-in ash cleaning function.

① SZL boiler using chain grate, mechanized loading and deslagging, and is more suitable for wood pellet/briquete fuel, rice husk, coal, palm kernel shell;

② SZW boiler using reciprocating(step) grate, mechanized loading and deslagging, and is more suitable for low-quality biomass, high humidity wood waste, wood chips, sawdust, bagasse, EFB, palm fiber, forest biomass, solid waste, com cobs..
