  1. Rays lose Griffin Jax before game, then use team effort to beat Seattle – Tampa Bay Times rawchili.com/mlb/774172/ #Baseball #Section:Sports #Section:TampaBayRays

  2. I went out for lunch today - a Friday tradition - and saw something that is a pet #peeve of mine. I'm going to explain why it is bad and why you [1] should not do it.

    At a #restaurant or similar establishment, DO NOT ask the #host / #server to #seat you in a section which is #closed. You may want to because it's "quieter" there, or you think you're doing everyone a favour because you won't disturb others or whatnot. But the reason it's closed is because the management doesn't anticipate enough business to keep it open, and therefore doesn't have #service #staff on to handle it.

    If you end up seated there, you're making the servers have to run back and forth between that section (to check on you) and the one they're actually supposed to be serving. It creates a lot of extra work for the #server, and makes the service worse, both for you and for the customers in the open #section, because of the time they waste going back and forth.

    A lot of servers/hosts are too polite to just say "no", especially with small independent businesses, so they'll seat you there, and everyone suffers. And then their #tips suffer, too, because of the degraded #service.

    Don't be that #asshole. Be #seated where they put you.

    [1] Well, not *you*, you're #lovely. You're reading this, so you're in the fediverse, and on an instance that hasn't been blocked or defederated, so you're probably a pretty good person. Apply this lesson to friends, colleagues, relatives when you go out together.

    Answers for protecting pressure parts

    1. The two ways you can minimize overheating, thermal stress and corrosion in your boiler are:

    ........ 1. ___Balance the firing rate to the fluid flow.

    ........ 2. ___Monitor metal temperatures throughout the system. This will help avoid temperature imbalances which cause thermal stresses and corrosion.

    2. The water should be a minimum of 70 F and must be within 100 F of boiler metal temperature.

    3. It is very important that you DO NOT suddenly increase air flow to a tripped burner. Maintain the same air flow as at the time of the trip for an extended period of time. Prior to re-establishing the burner flame, you may have to post-purge the burner.

    4. Dark and smokey flames indicate that fuel is not being completely burned. Once again, DO NOT suddenly increase air flow to the burners. Rather, you should reduce the FUEL FLOW so that it matches the existing air flow.

    5. Anytime the boiler is fired, the furnace must have at least 33% of rated full load flow in the tube circuits.

    6. You should make sure that the rate of change in the fluid temperature at the convection pass outlet does not exceed 200 F per hour. Any rate higher than this will lead to thermal stress problems.

    7. You can detect a tube failure by monitoring the high makeup flow rate or by a discrepancy between feedwater flow and main steam flow.

    Air ejectors and heat exchanging equipment containing copper alloys should not be in direct contact with the treated water for any long periods of time.

    During the wet storage period, a positive pressure nitrogen cap should be maintained on the system. When the unit is drained following hydrostatic testing and layup, nitrogen should be used to displace the water.

    In the foregoing we have stressed the importance of protection of pressure parts as such protection relates to operating reliability. We discussed ways in which you as an operator can contribute to safe and reliable operation of the unit. We hope that this section of the manual has made you aware of the damaging effects of corrosion, overheating, and thermal stresses, and more specifically, what you as an operator can do to protect the boiler pressure parts.

    STORAGE PROCEDURES

    In the presence of moisture and oxygen, atmospheric corrosion of ferritic materials (tube metals) proceeds rapidly. This not only makes the unit difficult to clean up during initial startup after a layup, but it also results in rough internal tube surfaces, which in turn serve as sites for future operational corrosion and deposition. Since it is impossible to completely dry all circuits, wet layup with treated water normally offers the best method of protection.

    Hydrostatic testing and layup should be accomplished with treated demineralized water. Treated demineralized water is defined as water which has been passed through a mixed bed demineralizer system and has ammonia and hydrazine added to give initial concentrations of 10 ppm and 500 ppm respectively. It is not necessary to maintain concentrations at these levels. Protection is still afforded after pH and hydrazine have dropped to lower levels.

    In preparation for the storage period, the ammonia and hydrazine should be added in a manner that results in a uniform concentration throughout the system. The hydrazine and ammonia can be added at the condensate header. It is recommended that if the unit is down five days or longer (long term) the unit should be prepared for storage with treated water during downtime.

    For contemplated shutdown periods from 1 to 5 days (short term), when circulating to cool down the steam generator, ammonia and hydrazine concentrations should be built up in the system to 100 ppm and 25 ppm respectively. To prevent unnecessary decomposition of hydrazine, the system should be cooled to less than 400 F before adding the hydrazine. These concentrations of chemicals can generally be reached by use of the cycle chemical feed pumps (during the time of adding the ammonia and hydrazine, the demineralizers should be bypassed).

    boiler purged. If the boiler is to be kept hot, circulation should be stopped, fans turned off, and all dampers closed.

    NOTE: the boiler can be force-cooled if desired, but cooling rates should be limited to 200 F/hr temperature differentials to prevent thermal stress problems. Circulation should continue in the cold cleanup mode. Heat should be rejected through the bypass system to the condenser at a rate determined by the flashtank pressure setpoint. A lower setpoint will result in a higher rejection rate. Air flow can also continue, but care should be taken not to overload the gas recirculation fans (hot gas fans), with cold air.

    The combination of air flow and heat rejection from the flashtank should be carefully regulated so that fluid temperature at the convection pass outlet does not change by more than 200 F an hour.

    After the boiler has been cooled, it must be properly stored. Wet storage, with all circuits flooded is preferable unless ambient temperatures will drop below freezing. If the boiler needs to be drained, it should be drained and stored under a positive pressure nitrogen cap to keep air out of the tubes to prevent oxygen corrosion.

    PROTECTION OF THE REHEATER

    Due to the various piping and valving arrangements of the reheater, it is normally impossible to pressurize the reheater with nitrogen. Therefore, the following procedure should be observed. Before shutdown is complete and the reheater is hot enough to produce steam, open the vents or drains on the primary inlet of the reheater. The condenser vacuum will facilitate in the removal of the steam/condensate in the reheater.

    these circuits will not exceed 1000 F, provided the leakage rate does not exceed 3%. If a tube leak is detected, the boiler should be shutdown as soon as normal operating conditions permit. Operating with a known leak can be dangerous as well as costly. If the leak is in the burner area, it can cause loss of ignition and possibly an explosion on re-ignition. Operating with a leak can also cause extensive damage and failure of other tubes by eroding adjacent tubes and by altering flow distribution enough to result in wide-spread overheat failures.

    Tube failures may be detected in several ways. If the leak is large, a loss of water from the system may be detected, either as high makeup or as a discrepancy in feedwater flow to steam flow. If the leak is in the furnace, it will often be seen as an unusual increase in riser temperatures.

    SHUTDOWN AND STORAGE

    Proper shutdown and storage procedures can also help protect the pressure parts against thermal stress and corrosion. Soot should be blown whenever possible immediately prior to shutting down. This will help remove corrosive deposits from the tube surfaces. The fuel/air ratio and furnace conditions should be closely monitored at low loads for explosion prevention.

    The normal shutdown procedure would be to reduce load to minimum feedwater flow with the turbine valves, and then lower turbine loading with the bypass system. Minimum FW flow must be maintained at all times in the furnace and convection pass enclosure circuits. The bypass system should be in the startup mode for maximum heat recovery in the feedwater heaters. The rate of change of fluid temperature at the convection pass outlet should be limited to 200 F/hr and SSH tube leg temperatures closely monitored. Below 10% of rated steam flow, the gas temperature at the thermoprobes should be limited to 1000 F. The turbine and boiler should be tripped at minimum turbine loading and the
