Too bad NASA didn't use cenospheres rather than square tiles on the space shuttle. There are some cenospheres located in the shuttle nose cone but that technology was developed over 20 years ago. Recent developments make high strength semi-rigid heat resistant heat shields from bonded...

Good question. Here's hoping some knowledgeable person will present an informed answer. Improves fossil combustion efficiency with co-invented cost effective combustion monitor. Reduces NOx, CO, LOI, opacity. haclift@yahoo.com

Yes. We have learned a lot in the past year. What we learned: Maintain the proper fuel air mixture throughout the boiler, horizontally and vertically continuously as the fuel passes through the boiler for each burner. Efficiency will optimize, NOx will be reduced, CO will reduce, ash will have...

As co-inventor of a flame combustion monitoring system that was successfully tested in 2002 - Guess what. I contacted all known environmental groups for help in propagating the business. The sooner we improve the environment the better. So I asked for help from every known environmental...

Perhaps the response has been limited because there is limited agreement with the conclusions from your test. PV=MRT is the equation which describes the apparent result of your test. The colder the air, the more dense the air and thusly the more oxygen in the fuel air mixture. Not surprisingly...

I can think of no application where a pilot is required. Continuously lit pilots are a lazy, hazardous, unreliable, cheap but expensive (inital cost is low, operating cost is not, safety features are defeated by heat generated when repeated attempts to light off fail). My opinion does not...

Oxygen probe location and number, length, and spacing of probes per duct is usually the most controversial subject to be faced throughout the duration of the installation. Whatever the decision must be continuously defended on a scientific basis. Selection of oxygen sensor supplier is the...

gregclock (automotive) I assume you would likewise conclude that any racecar automobile that injects nitrous oxide into the combustion chamber runs backwards!!

Thanks, Spector(Mechanical), for your response. As professionals, we are here to protect the public, not to please the boss and temporarily line our pockets, or matter of factly, feed our families on the blood of someone elses. Suppose the local hospital decided, rather than close their doors...

KISS Keep it simple stupid! THINK! The safety relief valve is always required. No exceptions in all states where the law of physics applies. Suppose, for example, a filled vessel is closed. The sunlight shines through the window, a nearby fire occurs, an electrical or chemical hazard...

Contact B&W, Cleveland, Ohio

Absolutely! I believe that category includes cenospheres. Float on water. MSDS sheets available. A source for cenospheres in that size range is: Brad Simmons, President Simmons Cenospheres West Hwy 11E, Lee Highway Abingdon, Virginia 24212 Another source is: Lyler Hartsock, PhD, Plant...

Prior to proceeding visit an existing facility and ask tough questions. Visit the Columbus, Ohio power plant near Circilleville, Ohio. Several cities (Columbus, Ohio for one) have built electric generating facilities which produce electricity by firing a boiler with industrial waste. Most of...

How smsll a plant? Large expensive WWTP are no longer needed. We recently replaced a relatively new $12 Million wastewater treatment plant with the following processes. Treat waste water in two steps. 1. remove the solids a. settling b. mechanical filteration] c. reverse osmosis 2. Neuter the...

Flowdude, good question. What value is ME? Is it BS? The answer is in your question, "Go with the Flow, Dude" Nanotechnology sounds mechanical to me. Check it out with Newt Gingregh at his web site. It definitely has a future with very little past and no long history of...

Stock Solvera Forry, Cleveland, Ohio has some PLCs that are primarily used for Precipitator Controls. Minue driven, no programming experience required, very robust (snow, ice, heat, sulfur, flyash) and relatively inexpensive compared to Westinghouse, Bailey, Siemens. However, the Forry does...

It has been a while, but I did some research to prove/disprove how to best prevent nuts from becoming loose. Bottom line is this: After a period of time (1 yr +), all materials change and fastener integrity must be checked. Metals subjected to continuous heat will loose their...

What is the coolant media for the copper wire? Liquid of gas water or air Conduction, convection, and radiation are the three means of heat transfer. Each must be addressed separately.

Flame detection which can distinguish between coal flame and oil or gas ignitors has been a fleeting task for several years. It is mostly an art rather than a science. Physical arrangement of the detectors is important. However, the experts in the area as we speak are as follows: Flicker...
