We are in the process of gathering some quotes to perform an engineering study. Our issues is that the boiler mfg B&W is usually very expensive.
Does anyone know of any other companies that will due this type of study?

I have a law/code question. I work in the state of Georgia and under law there are 8 mandatory codes and 2 permissive codes (as stated on the state of GA DCA website). In the codes I cannot find where pressure piping is specifically talked about.
The main codes I looked in are International...
rmw,
One of the products is described as green wood sawdust from saw mills. As received it feels dry, but there is moisture in the product. I performed a very crude test by vibrating it for 5minutes with a set of sieves. The only sieves I had were #4, #24 and #50 mesh. 100% went through #4...
I am working at a facility that wants to co-fire sawdust along with pulverized coal in the boiler. The boilers maximum capacity is 250,000 lb/hr. The boiler is front wall fired with three compartments and under normal operating conditions only operates two of them. We have an initial...
DickDV, interesting comment. At one point a 125 Hp motor was installed with this fan.
waross, we are speeding up the fan to get more flow (cfm). The mfg is working to get me the fan curve, so that will help me with the power required. Smaller diameters yields less contact area, I didn't...
I have a belt driven hot air fan that is currently operating at 1288 rpm. We would like to increase the speed to 1400 rpm. The motor driving the fan has a nameplate that states 100 Hp/575V/60Hz/89.6 Amp/1785 rpm. The motor has a sheave that is 10.9” diameter and the fan has a 15” sheave. We...
Check out this link. It talks about the oxide film that gives titanium its corrosion resistance and what will and wont corroded titanium.

dvd,
we do not have the concrete under the steel when we are cutting the holes so we dont have the isssue of dulling the blade on the concrete. And we are limited with space so welding a clip on the side is not possible.
A flame cut hole and heavy square washer plate is something we might...
We are going to attempt to use a Rotary Broach bit, one made by Milwakee called "Hawg Bit". The holes are for anchor bolts so the precision is needed so the bolts sit snug in the hole.
What you guys have said is help full with the rotary info. But i am looking for some theory behind why you...
I am working on a project that requires holes 1-5/16" dia. 1/2" deep to be drilled in A36 steel. These holes being drilled are in the field, so we do not have the ability to use a drill press.
The contractor performing the work would like to tourch cut the holes instead of drill them.
Is...
gr2vessels...i am still here-thanks for the insight on coal sitting in behind the stainless steel deflector sheeting/drying out/then catching on fire...that is a very good reason not to use a method that i was seriously considering.
I don’t like the 1" top plate because that still does not...
I have a set of I-beams over a hopper that are used to support a hopper train car filled with coal(low sulfur). The car is positioned over the hopper and then dumps the coal over the I-beams and into the hopper.
I am looking to protect steel I-Beams from corrosion and errosion due to coal...

Check out the attached jpg. What you will see is the footprint of my slab. And to the lower right on the curved corner I have some holes that need to be properly dimensioned. The important items are there relations to each other, the distance from the edge of the slab and they are also on a...
I am creating a drawing and I need to dimension features to be incorporated into a concrete floor. I need to provide dimensions so the items can be placed appropriately in the concrete forms before the cement is poured.
What should I dimension from? What should I use as a datum? The edges...
I am trying to calculate the elongation of wire rope as a fuction of load. I understand that it will be based on the wire rope configuration, overall diam, number of strands and number of wires. Is there a formual out there for this?
