Introduction

  • Firewood, wood waste, log, coal, jute, solid waste fired boiler
  • Yuanda Boiler manufacturing DZH wood/coal boiler, also named the most stable & cost-effective boiler, could burning kinds of solid waste. It has capacity from 1ton 2ton 4ton 5ton 6ton 8ton 10ton for user factory production. With this wood boiler system, easy to achieve working temperature 140~250℃.

  • DZH solid fuel boilers meaning is "horizontal moving grate boiler", with fire tube & water tubes, low requirement for water quality; cheaper boiler than automatic boilers, need labor to feeding fuel and slag remove; But more stable runnig, suitable for solid fuel.

  • firewood steam boiler

  • Most importanly, This DZseries wood fired boiler has the advantages of "three pass wet back" "two wings-shape flue" "convex tube plate" "special furnace arch design upon fuels" "inertia gas-dust separation" "water-fire tube" etc, realize high efficiency and low emission. It's called as "Revolution of Industrial Boilers" by China and overseas markets.

  • Used in food & beverage, dairy products, edible oil, starch, tea, feed mill, rice mill, garments, chemical, pharmaceutical, paper, textile, wood processing, packaging, dyeing, foam, refinery, tobacco, plastic rubber, oilfield, autoclave, EPS, leather, battery, concrete, washing powder, soap, cosmetic etc...

Characteristics

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, almost 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
