Boiler problems
Thread Content
Hello, teachers. I plan to launch a project soon to produce plywood. The oven moves at a speed of 10 meters per minute, and the moisture content of the raw material is 20%. During the processing, the plywood passes through an oven at a temperature of 130 degrees Celsius, again at a speed of 10 meters per minute. I would like to ask experts what size of boiler is needed for this purpose. How can this be calculated? Which boiler manufacturers are good? Thank you; it would be great if a formula could be provided
Do you mean that the boiler provides heat for the oven? What is the required moisture content of plywood after passing through an oven?
Hebei Province is set to phase out coal-fired boilers with a capacity of 10 tons per hour; one should be cautious before installing such boilers. Heating can be applied for at the park.
Yes, the teacher said that for plywood heated in an oven using a boiler, the moisture content should be 20 percent; after drying, it can be reduced to 5 percent. Thank you, teacher. How is this calculated?
Does the teacher know how to calculate it? Thank you
The specific heat capacity of water (4.2 kJ/kg·°C) is multiplied by the 20%-5% difference in water volume (in mass, in kg), then by the temperature increase (approximately 100°C – the temperature of the plywood before it enters the oven); in addition, the latent heat of vaporization of water is taken into account (you can look it up online; I can’t remember the exact value). The result obtained is the amount of heat required per minute. Next, the heat loss from the heat source used to maintain a temperature of 130°C in the oven is calculated; by balancing these two values, the appropriate parameters for the boiler can be determined. That’s roughly how it works. Please, any experts passing by, feel free to add more.
It is recommended to consult an experienced person or a similar manufacturer to make a comparison.
Okay, thank you, teacher. Could you be more specific? It would be great if there were a formula along with the calculation process. My company is in the chemical industry, and the boiler I’m using was designed by the boiler manufacturer; however, the boiler turned out to be too large. I’m a bit skeptical now regarding that manufacturer. I hope some teacher who knows how to do this can carry out the calculations for me. Thank you

Do you need corresponding dust removal, ash conveying, and ash dump equipment for your boilers? Should we consider desulfurization inside the furnace?
