Exhaust bellows

Fig ure 5-16. Casing and connections are designed to minimize distortions, prevent cracking, and allow relative movement during warmup and cool down. This view of the exhaust casing shows the stainless-steel expansion bellows.

When the pilot exhausts to the atmosphere, a pilot-operated PR valve is fully balanced. Like the balanced bellows valve, therefore, its opening pressure is unaffected by back pressure, and high built-up back pressure does not result in chattering. 

If the pilot is fully balanced against the backpressure and the valve is connected to a dry system, then the pilot exhaust can be safely piped to the main valve outlet so that all emissions go to the exhaust system. As the pilot is kept out of the cold, the problems which occur on balanced bellows spring-loaded SRV in the same situation will not occur. 

Once the vaive is reassembled, the SRV is performance-tested and adjusted to the correct set pressure, and the blow-down is set. Alt bellows-type and spring-loaded valves exposed to back pressure are back-pressure tested to ensure the integrity of the bellows and gaskets on the exhaust side of the SRV.

The stove can be started and operated indoors with no exhaust fans and no odor of burning wood. We have taken the stove to India and the Philippines and cooked with the Turbo Stove in small villages and on conference room desks with no odor. While the Turbo Stove currently uses a 12 Volt 3 Watt blower, the power could come from stored compressed air, bellows, wind-up generators, photovoltaic, thermophotovoltaic, windup motors, thermoelectric or other sources. 

Turbine inlet C-face seal with pneumatic actuated cylindrical piece at end of hot duct. Two horizontal and one vertical segmented cylindrical piston ring seals at ends of new tee-slu )ed adapter. Eliminates face seal and bellows Accommodates relative motion Uses same type seal as turbine exhaust... 

The turbine exhaust E seal was replaced with a segmented cylindrical piston ring seal, which became typical of all other seals. The turbine vertical inlet face seal was replao with two horizontal segmented cylindrical piston ring seals between the turbocompressor and a new adapter. These seals, located above and below the hot duct, are the same type as the turbine exhaust seal. The tee-shaped adapter also interfaces to the hot duct with a segmented piston ring seal that replaces the hot duct bellows that was previously used to accommodate thermal expansion. 

Valve stem seals, cylinder liner gaskets, waterpump seals, bellows, exhaust emission control devices, carburettor needle tips, valves and diaphragms are other examples of where fluorosilicone or conventional silicone rubber are being used today.
