![]() ![]() The inner mold mine’s cavity with the bottom forms the deadlock type furnace camera. ![]() 14 security valve installation arrangement branch pipe.The guide path is located in water path’s cavity provides heat carrier’s flow to a heat-stressed leading pipe wall. There is also the safety valves mounting branch pipe (branch pipes) is located on the boiler’s case upper generatrix. The coolant’s addition and discharge– water is carried out through the ” reverse T2 water” (pos.8) and “direct T1 water” (pos.9) branch pipes, located on the boiler case’s upper generatrix. The bundle of flue-gas pipes is located in hydraulic path’s cavity. The internal cavity formed by boiler’s case and furnace is its hydraulic circuit (pos.7). Construction is located on a mounting frame (pos.16). ![]() In terms of design the boiler represents horizontally located combined and welded cylindrical construction consisting of an outer mold mine - the boiler’s case (pos.1 in figures 1 and 2), a hub with the bottom - boiler’s furnace (pos.2 and pos.3) and flue-gas pipes (pos.4) welded with front and back pipe walls (pos.5 and pos.6). The Eurotherm copper is a double-thread (reversible) copper: the first copper’s motion is formed by a reverse flue (furnace), flue-gas pipes the second copper convective part’s motion. Strictly speaking, Eurotherm coppers are fire-tube flue-gas boilers (although the term “fire-tube boilers”, or simply - “fire tubers”, has got accustomed to coppers of a similar design): there is a heat carrier in a steel plate, while heat transfer happens through fire and flue-gas pipes’ surface. They differentiate fire-tube, flue-gas and fire-tube flue-gas boilers. Fire-tube (gas-tube) boiler is a copper where fuel combustion materials pass inside heating surfaces pipes, and the water - outside of pipes. ![]()
