D-Style Packaged Boilers: Proven technology
The Denapak is a self-supporting, two drum boiler with watercooled furnace walls.
- Meets steam equipment design, fabrication and safety requirements (ASME, PED 2014/68/EU or EN codes)
- Natural circulation design, includes integral steam and lower drums
- Flexible, reliable construction
- Seamless tubes form a thorough seal where they meet drums to eliminate heat-affected zones caused by welding
- Evaporator screen protect superheaters against direct radiation
- Optional installed feedwater preheater in the water drum to avoid flue gas condensation
- For increased efficiency, the Denapak is equipped with an economizer
- Preassembled and hydro-tested in the workshop prior to transportation
