Smoke tubes and wet bottom steam generators
The steam boiler WB has the following features: production from 2.000 to 20.000 kg/h, boiling pressure 12 to 18 bar, wet bottom to eliminate maintenance cost , lost of heat by radiation and overheating of rear pipe plate. Eccentricity of the furnace towards the bottom. Absence of pipes in the lower section to facilitate the cleaning on the water side. Large diameter furnace tube to improve yield and observe the environmental standards for flue exhausts. Three smoke turns to increase yield. Flanged and then normalized tube plates. Flangings absorb the body and tube nest expansion uniformly acting as compensators. Smoke pipes are expanded and welded at tube plates. Inside each hole, proper offlets are provided to allow each pipe to act both as studs and compensators at the same time. A full rod ASTM A105 * 50 studs held the tube plate and the rear smokechamber plate. The large diameter cylindrical shell is supplied with manhole, hand or man hole doors, intake pipes, couplings for auxiliary units and lifting eyebolts.
