A bidirectional excess flow valve for automatically stopping delivery of a fluid from a supply in a fluid network. The valve has a housing defining an interior forming a fluid passageway along a flow axis between a first opening and a second opening. The valve also has a valve seat in the interior, the fluid passageway extending through the valve seat, and a first and second shutoff element disposed on opposite sides of the valve seat. The shutoff elements are set apart from the valve seat assembly in an open position to allow flow through the fluid passageway. In a closed position, the first or second shutoff element is configured to move against the valve element assembly to close the fluid passageway when flow through the fluid passageway exceeds a predetermined level.

An easy-access blower assembly is disclosed. The blower assembly includes a blower enclosure, and a blower slider assembly mounted to the blower enclosure. The blower slider assembly has slider rails, each with a moveable rail and a stationary rail, a blower mounting plate coupled to each moveable rail of the slider rails, and a blower motor and fan assembly mounted to the blower mounting plate wherein the blower motor and fan assembly is adapted to slide out of the blower enclosure. Blower slider assemblies and methods of servicing a blower motor and fan assembly are also provided, as are other aspects.

Accessible blower assembly, blower slider assembly, and methods

A solid oxide fuel cell module contains a plurality of integral bundle assemblies, the module containing a top portion with an inlet fuel plenum and a bottom portion receiving air inlet feed and containing a base support, the base supports dense, ceramic exhaust manifolds which are below and connect to air feed tubes located in a recuperator zone, the air feed tubes passing into the center of inverted, tubular, elongated, hollow electrically connected solid oxide fuel cells having an open end above a combustion zone into which the air feed tubes pass and a closed end near the inlet fuel plenum, where the fuel cells comprise a fuel cell stack bundle all surrounded within an outer module enclosure having top power leads to provide electrical output from the stack bundle, where the fuel cells operate in the fuel cell mode and where the base support and bottom ceramic air exhaust manifolds carry from 85% to all 100% of the weight of the stack, and each bundle assembly has its own control for vertical and horizontal thermal expansion control.
