Catalytic cracking device is a refining device that excessive heat and more high-grade energy, the energy recovery impact in the energy saving is very notable. Catalytic cracking exhaust heat boiler compared with ordinary medium-voltage boiler has biggish distinction, catalytic cracking waste heat boiler besides recover regeneration sensible heat, protecting the environment, also bear the task that superheat all the saturated steam from the device, its design must combine different situations of regeneration process, and flue gas properties and its own characteristics of steam system to satisfies the requirements of process unit under various working conditions. Technical features
Adopting rational optimization structure layout mode, undertake all saturated steam heating task of catalytic cracking device and water feed heating task of all the steam equipment.
Adopt combining method of macro regulating and micro regulating, solve the problem that big change of steam water loading range.
Add bypass and other special design, solve regeneration gas load, composition greatens;
By adding preheater and new anti-corrosive materials, effectively preventing the boiler heating surface corrosion by low temperature.
Adopted advanced and efficient soot-blower technology, can solve heating surface deposition problems;
Adopt heat exchange tube of high-efficiency heat transfer performance and furnace micro positive pressure design.
