So I'm not sure whether to next get a 2-1/2 ton single stage, which one tech said would be neither here nor there, or to get a 3 ton 2-stage unit, and perhaps wire it to keep the blower on high in both stages if I ever start using & cooling cooling the 2nd floor–unless that would hurt the humidity situation too much.

The two stage design is preferred because; 1) the single stage design results in significant levels of unoxidized carbon exiting the roaster, reducing gold recoveries and 2) the two stage design allows the most efficient utilization of oxygen.

Single-Stage Two-Stage Even, Two-Stage Comfort COMFORT ZONE Consistent temperatures for consistent comfort. American Standard furnaces, such as our Platinum 80, Gold 80V and Gold 80 models, feature multiple stages of heat that typically run at lower, more efficient stages. In fact, they only step up to additional stages on the coldest of days.

One-stage surgery provides and prioritizes the benefit of elegance but involves a higher risk of failure, while two-stage dental implant requires two surgical procedures yet provides a higher rate of success. Whether to have a one-stage or a two-stage implant procedure depends on different features, such as aesthetic scrutiny and bone quality.

These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semiautogenous-ball-mill-crushing (SABC) circuit, and the application is well described (Mainza et al., 2012). This section refers to high-aspect AG/SAG mills.

Two-stage series/parallel pumps are really 'two pumps in one". When operated in the VOLUME (parallel) position, they mimic the design of the single-stage pump. In the PRESSURE (series) position, they will flow up to 70% of their rated capacity more efficiently (with less engine speed) than a single stage pump.

The working mode of the two-stage burner is small fire-high fire, first light the small fire, and then light the large fire after the small fire is stable. That is to say, the burner has two working points, that is, it can work in one-stage fire (small fire) or two-stage fire (large fire). There are three states of high fire, small fire, and stop.
