They did the same with a stuffed grey squirrel (a possible nest predator).

Fire-tube (gas-tube) boiler is a copper where fuel combustion materials pass inside heating surfaces pipes, and the water — outside of pipes. They differentiate fire-tube, flue-gas and fire-tube flue-gas boilers. 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. 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. Copper’s design 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). Construction is located on a mounting frame (pos.16). The internal cavity formed by boiler’s case and furnace is its hydraulic circuit (pos.7).

The bundle of flue-gas pipes is located in hydraulic path’s cavity. 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. There is also the safety valves mounting branch pipe (branch pipes) is located on the boiler’s case upper generatrix. The guide path is located in water path’s cavity provides heat carrier’s flow to a heat-stressed leading pipe wall.

PSI’s Technology Assessment Group carried out an and assessed its performance in various application scenarios. Latest News In a stakeholder event representatives from research and industry were able to gather information on the results of the joint project (Thermally Driven Heat Pumps for Substitution of Electricity and Fossil Fuels).

The inner mold mine’s cavity with the bottom forms the deadlock type furnace camera. The smoke fumes return to a door from the bottom and pass inside flue-gas pipes (pos.4) where vortex generators are set (pos.17) while turning, come into smoke fumes’ case (pos.11) and removed into atmosphere through a branch pipe from there. The furnace door (pos.10) is hung from the boiler case’s front side of on special loops (pos.21). Loops provide door’s opening, both to the left, and to the right, as well as reliable multiplexing inhaling possibility. From a furnace’s side The door is protected by heat resisting concrete (pos.13) isolation plate, while playing the role of smoke fumes’ titling chamber upon their transition from boiler’s furnace to flue-gas pipes.
