Project address: Indonesia
Name of boiler: 20 t/h chain grate boiler
Application areas: paper industry
Project description: The 20ton chain grate boiler for paper mill by boiler steam
ZBG 20ton chain grate boiler can be used for paper industry processing. On a paper machine, steam produced by a chain grate boiler is used to dry the sheet of paper to a target moisture content before it is wound up on large rolls that can be transported, stored and shipped.
Chain grate boiler features
1. New furnace structure avoids to produce bulge defects which happens because of direct heating the bottom of the drum.
2. Avoid flue tube plate crack
3. New arch design for inferior coal combustion and coal adaptability
4. Independent adjustable wind chamber under the fire grate, and wind comes from two sides. Ventilated section ratio reaches 100%, and can be adjusted flexibly and air flows evenly.
5. Push-pull type damper ash removal device effectively prevents deformation of the secondary combustion and grate air leakage.
The main technical data of 20 t/h Chain Grate Boiler
1) Rated evaporation:20t/h
2) Rated steam pressure:1.25 MPa
3) Rated steam temperature:194 ℃
4) Feed water temperature:105℃
5) Cool air temperature: 20℃
6) Exhaust gas temperature: 166 ℃
7) Design thermal efficiency: 80%
8) Design fuel: Rice husks is required to dry(water≤20%)
9) Grate area:17.7 m2
20ton chain grate series is ideal thermal equipment for the paper factory processing, sugar industry, textile industry with advantages as follows: high automatic level, high thermal efficiency, equipped with dust removal equipment, less pollution of the environment.
