Industrial Fuel Coal Rice Husk Steam Boiler 4 Ton Per Hour For Rice Mill Plant

Product Specification

Industrial Fuel Coal Rice Husk Steam Boiler 4 Ton Per Hour For Rice Mill Plant
Brief intrduction of rice husk steam boiler
DZL series boiler is low pressure horizontal type single drum automatic travelling chain grate stoker fire and water tube boilers. The steam capacity ranges from 500kghr to 35ton per hour. The chain grate boiler are suitable for fuels coal, small size biomass fuels, wood fuels, pellets, such as rice husk, wood chips, etc.
4 ton coal fired steam boiler is the best sale boiler model for rice mills.
Basic parameters of rice husk steam boiler

Rice husk steam boiler design advantages:
1.5-8% Higher Efficiency
Our DZL boiler is 5-8% lower fuel consumption, and save at least 5% investment on boiler operation compare to other solid fuel boiler.
2.Self-Protection On Power Failure
Natural circulation prevents the water wall from vaporizing and prevents damage from accidents without special protective measures.
3.Assure 30 years life span
1st grade dust cleaning effect protect boiler long life span.
4.Low original dust discharge concentration
Design with large volume furnace and firing chamber make fuel combustion sufficient, low fuel consumption.
5.Double layer 12cm aluminum silicate insulation , reduce heat loss, control the boiler body temperature below 40 ℃.
Rice husk steam boiler core technolody
1.The boiler has big drum and have big enough space for water. Compared with the SZL series, the DZL boiler is more adaptable to poor water quality. Moreover , when the boiler scaled, it is convenient for maintenance.
2. Adopting convex tube plate, prevent tube plate cracking and simplify the structure of canceling the tension bar.
3. The Wing-shape flue arrangement, the flue gas is three pass, reduce the smoke temperature of high temperature area tube plate, thereby preventing the cracking of tube plate and Boiler tube explosion.
4. Adopting threaded smoke-tube technology, strengthen heat transfer, reduce the number of pipes and the size of boiler shell; reduce the thermal stress at the end of the pipe, and prevent cracking of the tube plate. At the same time, due to the self-cleaning ability of the flue gas in the threaded pipe, avoid the accumulation of dust in the tube.
5. The boiler has sufficient output, fast speed heating and high thermal efficiency.
Boiler system: we provide this rice husk steam boiler with full set auxiliaries.

Economizer
Aluminium-steel Fins with high conductivity co-efficient.
ND steel sheel to prevent the corrosion of sulfur
Aluminium Silicate insulation, release heating loss, reduce economizer outer cover temperature.
Large size heating area, adequate heating exchange area, greatly make use of heat energy of exhausted gas to heat feed water, increase boiler efficiency;
