Modern industrial boiler designs offers several benefits. In the past, improper design of boilers has causedÂ explosionsÂ which led to loss of life and property. Modern designs attempt to avoid such mishaps. Further, mathematical modeling can determine how much space a boiler will need and the type of materials to be used. When the design specifications of a boiler are determined, design engineers can estimate a cost and time schedule for the construction. Â Our Industrial Boiler designs are use for all types of applications as process boiler to provide energy to the plant and itâ€™s processes without having to rely on local utility boilers, which incur electrical costs that some plants are unwilling to stomach. Â The return on investment for an industrial boiler in a plant can be staggering, especially in the case of Biomass fuels or other alternative energy sources.
Industrial boilerÂ designs may be based upon:
- Production of a maximum quantity of steam with minimal fuel consumption
- Economic feasibility of installation
- Minimal operator attention required during operation
- Capability for quick starting
- Conformity to safety regulations
- Quality of raw waterÂ : how hard or soft the water is will determine the material of the boiler.
- Heat source â€“ the fuel to be burned and itsÂ ashÂ propertiesÂ or the process material from which the heat is to be recovered.
- Capacity / steam output required, usually measured in tonnes per hour or kg/sec.
- Steam condition â€“ pressure, temperature, etc.
- Safety considerations
- Mechanical constraints
- Cost restrictions
- Monetary cost
- Tensile strength of material must be considered while using any joining processes.
Accessories and mountings are devices which form an integral part of anÂ industrial boilerÂ but are not mounted on it. They include economizers, superheaters, feed pumps and air pre-heaters. Accessories help in controlling and running the boiler efficiently.
Certain common mountings include:
- Feed check valve â€“ regulates the flow of water into the boiler and prevents the back flow of water in case of failure of the feed pump.
- Steam stop valve â€“ regulates the flow of steam that is produced in the boiler to the steam pipe, and may also be used to stop the supply of steam from the boiler
- Fusible plugÂ â€“ placed at the lowest level of water and above the combustion chamber, its function is to extinguish the fire as soon as the water level in the shell of the boiler falls below a certain marked level.
- Safety valves â€“ automatically prevent the steam pressure from exceeding safe levels
- Water-level indicators â€“ indicate the level of water in the shell
