To meet New York City emissions regulations and secure a sustainable future for their plant, the 4th largest high pressure steam plant in NYC chose Preferred for its #6 oil to gas and #2 oil conversion.

This plant has a rich history, with four (4) watertube boilers stamped 1939, traditionally burning #6 oil except during World War II when they burned coal because oil was going to the war effort.

Pictured Below: Old panel on the left, new panel on the right- This is one of five new panels. We accommodated the customer with the same look of the old panel, but with state-of-the-art technology.

With (4) watertube boilers and (4) 60,000 gallon, single wall tanks buried 15 feet underground, they had some work to do in order to convert from #6 oil to gas and #2 oil by 1/1/2020, when NYC enacts fines for facilities not in compliance with emissions regulations.

Preferred met the challenge with new oil guns/tips, a complete and new fuel oil system, Allen Bradley PLC combustion controls to replace their old Bailey single-loop controllers, and EPA, DEC, DEP compliant tank gauging system for the single wall, buried tanks.

Spreading Combustion Joy through compliance and innovation!

 

Preferred’s R&D department made such significant improvements to the JC-30D opacity monitor, we re-branded it the JC-30D-EZ. The new opacity monitor is EZ to install, EZ to setup, and EZ to calibrate.

What’s New?

  • With the new LED light source, there is nothing to adjust on the light source side of the opacity monitor. So the adjustable mount has been replaced with a rigid pipe mount.
  • Because the new detector lens is directional, the new receptor can’t see ambient light coming in from severe angles, so the light shields are not required anymore.
  • The electronics in the light source have been improved to allow calibration from the display. The DIP switches, pushbutton, and potentiometer are gone, so calibration can be initiated from the display on the ground and there is no need to go up on the stack anymore.

The JC-30D-EZ can be set up to auto-calibrate every time the burner shuts down to compensate for increasing soot on the source and detector lenses. This means lenses can go up to nine times longer between cleanings!

Dirty lenses can cause high stack opacity shutdowns on previous, and competing opacity monitors. The JC-30D-EZ’s ability to auto-calibrate itself to adjust for dirty lenses makes a high opacity shutdown much less likely.

Congratulations to the R&D department for making the JC-30D-EZ best opacity monitor on the market. We especially want to share the good news with New York City, Boston, and elsewhere where opacity monitors are required by code. The new JC-30D-EZ can be retrofitted to older JC-30 opacity monitors, and it can replace existing Smoke Watchman units.

Diesel Exhaust Fluid (DEF) was developed to help keep heavy-duty diesel fueled machinery like boilers operating within federal emissions standards. At the chemical level, DEF is a combination of 67.5% de-ionized water and 32.5% urea that transforms harmful nitrous oxide emissions into harmless water and gas.

Urea is an organic chemical compound produced as waste by the body after metabolizing protein—but the urea used in DEF is not (despite some confusion on the subject) derived from human or animal urine. For nearly two centuries, scientists have been able to create synthetic urea, which is much more appropriate for the DEF application.

DEF isn’t actually a fuel additive, and it never comes in contact with diesel. Rather, it is stored in a separate tank and is pumped into the exhaust stream of diesel machinery to break down dangerous NOx emissions into safe nitrogen and water. This process is called Selective Catalytic Reduction (SCR).

Changes in EPA emission standards have required diesel burning machines to reduce their output, and SCR is the technology of choice for this purpose. As emission standards have continued to expand to include off-road vehicles, generators, and a variety of engines, the use of DEF is becoming more and more widespread.

To properly deliver DEF, the Diesel Exhaust Fluid Urea Pump system is designed to safely and effectively transfer DEF fluid from a tank to diesel equipment, helping facilities comply with strict NOx emission regulations. Constructed using stainless steel piping and pumps, the DEF system lasts in even the most abusive outdoor environments. We proudly make DEF Urea Pump Systems in the USA. Here are the specifications:
