Introduction
The DZL-VII water-fire tube boiler developed by Yuanda Boiler is a quick-installed environmentally friendly and energy-saving boiler. It was jointly developed by our company and Professor Li Zhiguang, a famous boiler expert and director of Beijing Zhiguang Boiler Research Institute. After 30 years of research and practice, it has become a leader in similar boiler products.
It is called "the revolution of industrial boilers". This type of boiler can burn a variety of fuels, biomass/wood pellet, firewood, log, briquette, wood waste, wood chips, sawdust, bagasse, rice husk, palm kernel shells, palm fiber, waste fabric, jhute, coconuts shell, wine lees, corn cobs...
The boiler has a compact structure, easy installation, low engineering cost, automatic operation, sufficient boiler output, and high efficiency. It is currently the most popular equipment form in industrial steam/hot water boilers.
Yuanda biomass boiler is mainly composed of 5 parts: Boiler proper, Fuel feeding and combustion system(grate stoker), Water treatment system, Air and flue gas system, Control system.
It can be equipped with automatic sewage control, steam/water flow meter, automatic ash collection and removal device, as well as installation materials and engineer guidance.
We customize reasonable feeding methods, grate stoker, furnace arches and dust removal & soot blowing solutions according to different fuels.

Boiler Advantages
01
Three pass gas flue structure & Arched tube plate
1. Three pass design extends the flue gas distance, strengthen the thermal transfer efficiency; 2. Arched tube plate increases the toughness of the tube sheet, prevent end cover cracking
02
Spiral Fire Tubes(Smoke Tube) Technology
Use the advanced technology which is our patent to design the spiral tubes, to enhance the boiler thermal power 10% higher than normal, and avoid the spiral tube from ash deposition and wearing
03
Fully automatic chain grate combustion
Use big piece fire grate, air supply sufficient and evenly, tight connection, no leakage, avoid loss of calorific value and affect boiler thermal efficiency
04
Economizer Design, Energy Saving
1. Recycle exhausted smoke to heat feed water, increase feed water temp then save fuel cost at least 6% per hour 2. Reduce chimney smoke temperature
