I need to develop an economical small preheat exchanger on the exhaust of a 1400F oxidizer/burner @ 300scfm inlet airflow expanded to ACFM @ 1400F.
I need to keep the DP low
I will run at 1400F inlet on the hot side and 150F inlet on the cold side.
Questions I have:
Is there a simple generic...
Is it legal for a licensed electrician to replace a capacitor in a single phase explosion-proof motor? Baldor stated today that the motor looses its UL rating unless the capacitor is replaced in a UL motor shop. Very inconvenient for a 10 minute repair.
The motor capacitors are replaced by...
We have a 4" and 6" groundwater recovery pipe header that is approximately 3000ft long. Historically, 15% HCL mixture has been pumped through the pipe in 5000 gallons shots to loosen the scale. The pipes are Fiberglass and now require additional treatment. We are considering switching gears...
I have a question on having engineer PE seals applied and when it is applicable.
First, we are an OEM and we manufacture various pollution control equipment. One piece of equipment is a flare which is self supporting. We have done the due-dillengence of having a PE run calcs and verify the...
I am doing a slab for (2) 20K concrete tanks. The tanks are 10'6" diameter each and total weight with water is about 25,000# each.
I need to design the slab to support the weight. The slab will be 37'x37'x6" thick, but I was going to do an interior support that is about 24' x 12' x 9.5" thick...
I have an Aluminum blower that has TCE fume passing through it at roughly 2500ppm at a flow rate of 600cfm. The blower wheel and housing is Aluminum. The wheel and fan internals have a surface area of approximately 7.5sqft.
I am trying to calculation a rough estimate of rate of corrosion...
I have an application where we have a quench scrubber before a tower. The temperature probe between the quench and scrubber is Inconel 600 and after about 1 week, it looked sandblasted and came apart. The operating temp is about 120-175F and no higher. The quench water will have relatively low...
We are treating chlorinated compounds through an electric cat ox. The heating chamber raised the temp to 800-900F and is manufactured from 304. about 2' downstream the material changes to AL6XN and temp up to 1000F. HCL is generated as the gas passes through the cats and the AL6XN is...
We have historically manufactured 5-150HP blower base frame packages from carbon steel. We are transitioning to AL. These base frames typically consist of a motor direct drive to a blowerhead on a frame. By changing to AL, we have agreed that we may need to beef up the frames accordingly, but...
Looking for someone who knows a contact or contact co. with resources in Beijing China for RedLion Datastation controls. We have some connectivity issues and need a rep onsite.
I am looking for anode sheet material supplier for building small hydrolysis cells to make O2 by submerging the anodes in water. I have a source from denora, but the plate material is >$1K for a single 24" x 35" sheet x .060. I expect a premium, but don't want to send a sales guy on vacation...
I have a simple slab about 40x70 that will be 6" thick for general walking traffic.
There is a 38'x 20' section of the slab that will have some heavy equipment. There will be a 3500 gallon vertical tank (6'D) that weighs about 32,000# full of water.
Can someone please advise on some quick...
I have a proeject with about 4000 linear feet of 3" conduits that my client wants to pull the hose through the conduit as the conduit is laid in the ground vs. completing the piping project and pulling the hose later. There contention is that 2-3 of the runs are 300-400 feet each and it will...
I have (7) enclosures going to a site in Kentucky along the Ohio river. The enclosures are 36"D x 72"W x 72"H and are fabricated aluminum skinned enclosures with an open bottom. We will have water pipes inside which are critical so we need to place a heater in each enclosure. I am trying to...
I have a treatment system my company built in NC last year. The connected power is 120/208V 3phase. There is a 20HP 3phase pump that draws from the system. The control panel has branch circuit protection for a 20HP drive and a 25HP rated drive operates the pump. The issue is that site...
I have a project where we will be injecting air into approximately 1000 2" sch 40 PVC well points. The wellheads will have approximately 5 - 12 psig applied . Each well head will need a flow measurement device, so we will manufacture an orifice plate to read flow. Our preference is to build...
I have a Centrifugal pump that peaks at 70psig @ 60Hz. The pump is doing no work at 70psig as the flow is almost zero. I need to increase the pump speed to get about 80psig. I think that going to about 70Hz or 4000RPM will give me the impellor tip speed needed to generate additional pressure...
I need to build or purchase a small high temperature rated damper or valve for bypassing a low flow around a heat exchanger. A 4" valve orfice is adequate. I found several companies that can supply valves for close to $10k. Anyone have a lead on a supplier that would have a reasonably priced...
We manufacture thermal oxidizers and we are getting into more diverse, "createive" applications. We have an electric unit that will oxidizer chlorinated compounds, thus generating HCL in the 0-500ppm range (typically 50ppm or less). The process elevates the temp to 1000F. We are looking at...
