A structure frame is used to support a heat exchanger of a steam generator, wherein a heat exchanger is formed by coil pipes, and the coil pipe is provided with a sloping portion, therefore water can be easily exhausted out from the heat exchanger when the steam generator is shut down. The structure frame comprises pairs of first support groups which are perpendicularly and obliquely extended, and the first support group is closely straddled on the sloping portions, and pairs of first supports are rigidly connected with second supports which are extended among adjacent sloping portions. The structure frame keeps the sloping portions in intervals, prevents the direct contact between the adjacent pipe surfaces, and is not attached on the straddled pipe portion, thereby providing the enough loose pipe support engagement, and permitting the free movement of the pipes generated by the different expansion and shrinkage rate of the structure frame.

A multi-plate clutch includes a plurality of friction plates that are rotationally coupled to a concentric shell wherein keys radially extending from each friction plate are slidably received in axial channels formed in the interior surface of the shell. The keys of all but one of the friction plates are dimensioned to have a relatively loose fit in the channels while the keys on a single friction plate are dimensioned to have a substantially tighter fit in the channels. This has a stabilizing effect on the entire stack without impeding the operation of the clutch. Rotational stabilization of the plates serves to dampen the impact of the edge of each of the keys of each of the plates against the channel sidewall during abrupt load changes in the drivetrain to thereby reduce wear and the generation of noise.
