Harvard harnesses CHP to meet emission reduction targets

Drew Gilpin Faust, the president of Harvard University, in 2008 committed her institution to a 30 percent reduction in greenhouse gas (GHG) emissions by 2016. Adding an 8MW gas-fired cogeneration plant, designed by Burns & McDonnel, to the 110-year-old Blackstone steam plant helped do the trick. More



Using the Right Boiler to Make Power Plant Economics Work

It’s tough to make the economics of a power plant work these days. Coal plants are largely out of the question due to regulatory restrictions that require the installation of very expensive equipment to reduce emissions. Even gas-fired plants can be a tough sell despite the low cost of natural gas in the U.S. More



UC-Davis boosts steam, reduces emissions

UC-Davis needed to boost steam output to meet campus expansion from 27,000 to 32,000 students, limit emissions below air quality standards, and ensure a continuous source of steam. So for its new Central Heating and Cooling Plant, it chose a boiler from RENTECH Boiler Systems. More



California builds high-efficiency CHP for downtown campus

When California needed a new CHP to provide electricity, steam, chilled water and compressed air for a downtown university campus, the requirements were stiff. Four boilers from RENTECH were selected to meet the challenge. More



Boiler Replacement: Custom or Off the Shelf

Typically there are two choices in selecting a boiler. One approach is to order a package boiler fabricated in the factory and shipped to the site for installation. The alternative is to obtain a “stick-built” boiler that is built on site. Package boilers are the less expensive option, but they come in standard sizes and are not optimized for specific site conditions and requirements. More



RENTECH Projects Win EPA Awards

HRSG systems from RENTECH Boilers were selected and installed at new CHP plants at two of the six winners of the 2011 ENERGY STAR Awards from the Environmental Protection Agency. More



TPC Group replaces aging boilers with RENTECH units

TPC Group of Houston realized an “immediate impact” when it replaced aging boilers with two new units from RENTECH Boilers, which prefabricated the D-style watertube boilers and assembled them on site for a 50 percent savings. More



Major overhaul of Rowan’s energy infrastructure

An engineering study for Rowan University in Glassboro, N.J., resulted in a cogen and central chiller plant with HRSGs from RENTECH Boilers to satisfy growing energy needs, reduce the cost of electricity, steam and chilled water, and minimize pollutant emissions. More



Amherst makes transition to cogen

All campuses need electricity, steam or hot water, and chilled water – it’s just a matter of how much. Amherst College, a small, private college in Amherst, Mass., with 1,400 students, considered CHP for years before deciding on a cogen plant that would pay for itself in seven years. It included an HRSG from RENTECH Boilers. More



Frito-Lay’s Commitment to Conservation

Frito-Lay North America, a business unit of PepsiCo, Inc., serves as a role model for conservation for the conglomerate’s other companies. At its production facility in Killingly, Conn., Frito-Lay installed a supplementary-fired HRSG from RENTECH to better manage its energy consumption and make it more competitive on the grocery store shelf. An important consideration in the industry is energy-per-pound of product. More



CHP replaces fired boilers at Smith College

When Smith College in Northampton, Mass., decided to renovate and reconfigure its central heating plant and steam distribution system originally built in the 1940s, it installed a vertical-design HRSG and a low-emissions packaged boiler from RENTECH. Now Smith College produces power onsite in a reliable operation that satisfies some of the nation’s most challenging environmental standards. More



HRSGs for small plants

Mention HRSG and most people in the power business think of triple-pressure units in service at large combined-cycle plants. But drop in size to HRSGs serving in small combined-cycle and cogeneration plants (those powered by GTs producing up to about 60 MW), and it’s another world in unique design variation. A leader in the supply of drum-type boilers for GTs rated up to 60 MW is Rentech Boiler Systems. More



Backup steam supply is critical for Calpine

In some areas of the country, a merchant plant capable of generating and selling only electricity can have difficulty turning a profit. Add a thermal contract and the revenue stream can change dramatically. However, a thermal contract means you must supply steam even when the gas turbine (GT) portion of the combined cycle or cogeneration plant is forced out of service. More



Self-generation at ASU

Many large consumers of electricity, including municipalities and universities, are considering the benefits of self generation because of the spiraling cost of energy. Arizona State University’s new combined heat and power plant includes an HRSG from RENTECH to stabilize power costs and guarantee a reliable supply of electricity, steam and chilled water. More



Reduce emissions in Texas

A chemical plant in Texas selected RENTECH to help reduce pollutant emissions. Four packaged steam generators from RENTECH were designed with minimal refractory to enable rapid startups and SCR to assure emissions compliance. The plant’s new cogeneration system allowed the company to retire its old steam generators and meet its compliance schedule. More



Energy for Corona

Corona, a city of about 125,000 people in southern California, established a municipally-owned power generation company as its answer to the state’s energy crisis. The goals included providing a reliable source of electricity, stabilizing costs, and controlling emissions. RENTECH developed a HRSG for this unique project to reduce installation time and cost, facilitate maintenance, and perform to the customer’s requirements. More
