Introduction
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.
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
