Paper Processing Industry




Steam is necessary for paper processing industry. Usually, steam is used for drying to improve the strength and smoothness of paper. The water content of wet paper still as high as 53%~70% after squeezing, and it is not useful by using mechanical stress for anhydration, so, use cast iron dryer to dry paper, cooperate with the use of steam boiler. Except drying, it can also use for corrugated paper processing, andsupport the use of calender and glue paste roller.


Uses of Boiler & Steam in Paper Processing Industry


Industrial Boilers Suitable for Paper Processing Industry


SZL Biomass Fired Chain Grate Steam Boiler


Capacity: 0.5~25t/h

Fuel: bagasse, wood, straw, rice husk, and other biomass fuels.


SZL double drum boiler adopts membrane wall and automatic feeding system, has the advantages of high thermal efficiency (97%), sufficient output, high steam quality, and low pollution. During the paper processing, there are large amounts of waste materials, biomass fired boiler could use these wastes as fuel, save cost.



WNS Oil Gas Fired Fire Tube Steam Boiler


Capacity: 1~30 t/h

Fuel: heavy oil, diesel, natural gas, LPG, city gas, coke gas, etc.


WNS series steam boiler smoke gas three pass and wet back structure, achieve high thermal efficiency (98%) . This is fire tube boiler, low water quality requirement, the failure rate is lower than 0.1. Adopts international excellent burner, PLC automatic control cabinet, and safety interlock device, operate safely and conveniently.



Circulating Fluidized Bed Steam Boiler

Capacity: 6~220t/h

Fuel: coal, wood, straw, and other biomass fuels.


SHX series boiler is a large capacity boiler, adopts the advanced technology of cyclone fluid combustion, cyclone separation structure & parametric design, and loop seal device, has advantages of energy saving, high thermal efficiency, sufficient output, and high steam quality. Moreover, the boiler could deal with the wastes (bark, waste wood material, black liquid) produced during paper processing through combustion, save operation cost.




Price of Paper Processing Industry Boilers


The price of paper processing industrial boilers is based on the capacity and accessories. Generally, the accessories of boilers include burner/grate, electric controller, steam header, water softener, BFW pump, platform ladder, and chimney, etc. If you would like to use the specific devices (brand, materials, quantity, etc.) or the additional equipment (air preheater, economizer, condenser, etc.), the prices are quite different. So, if you would like to get the exact price, please inquire for the details.


How to Select a Proper Boiler for Paper Processing Industry

 

1. Determine the capacity of the boiler. The boiler capacity should based on the Heating Load Curve or Heat Balance Diagram, and includes the heat loss in pipelines, self-used heat of boiler room, available used waste heat. While, usually, it is difficult to get the Heating Load Curve, the heating load could get based on the max thermal consumption per hour within production/heating/domestic, and then determine by using the coefficient.

2. Determine the boiler heating parameters, including pressure, temperature, etc.

3. Determine the boiler efficiency. In order to benefit for economic management, the boilers should have high thermal efficiency, and the boiler output, quantity and other performances have to adapt to the change of heat loading.

4. It is better to select the boilers with same capacity or combustion equipment. If different, the max limitation is two models, to decrease the problems of equipment layout and management.
