Boilers mainly provide heat to printing industry for production, heating and drying. Boilers used in printing industry are mainly two types: steam boiler and thermal oil boiler. Boiler’s fuel can be wood, coal, gas, oil, biomass etc. Wood, coal costs are lowest, but pollution is heaviest. Gas and oil cost are different in different places. Biomass is a new fuel with lower pollution.
How to Select a Proper Boiler for Printing 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.
