PROBLEM TO BE SOLVED: To provide an air blowing method in the heat treatment for rapidly raising the temperature of works, and uniformly heating or cooling the works.NISHIYAMA TOMOHIKO西山 智彦KITAMOTO KENICHI北本 健一ABE KOJI阿部 浩次FUJIWARA MINORU...
Why is my furnace not blowing hot air? My furnace fan blows, but no heat. There is no flame. It is a Comfortmaker. I have replaced the filters and shut off the breaker and turned back on. Fan still just runs but doesnt ignite and blow heat. Read more Tom Journeyman HVAC / R Serv...
But there is limit to the benefits of a very large bulk of slag, since this increases the iron loss due to burning, causes splashing and rapid wear of the lining. In a steel plant, regression equations based on operational data are employed to predict the end point for sulfur within ...
Had very little info on the part I needed but they pulled out all the stops to try and find it for me. The hunt was unsuccessful, but not for a lack of trying! Will be back for anything and everything going forward! ★★★☆☆☆ Vicki K 69 days ago Very friendly staff. Understood...
In such a “hot heel” practice, a significant fraction of liquid steel is left in the furnace for the next heat. Hot heel practice not only prevents steel from rephosphorization, but also speeds up the melting process; however, it has a smaller charge weight in the ladle as a drawback...

Furnaces that are ducted rather than blowing heated air directly out of the furnace into the space they heat are not as efficient because of the way they produce heat in a building. For example, a forced air propane furnace burns the fuel inside the furnace which heats up a heat exchanger...
This direct or indirect retaliation does not only seem to take place in the case of whistle-blowing as mentioned earlier in this report, but also in some minor cases of bad staff-management relations. daccess-ods.un.org 在有人举报的情况下,这种直接或间接打击报复不仅像本报告此前提到那 样似...

But a rise in the blast volume is limited by an increase in the pressure drop. High-quality burden and coke regarding mechanical and physical properties, their appropriate distribution at the furnace top, and higher gas pressure in the furnace are prerequisites for keeping the pressure drop on ...
