The USEPA announced today new proposed carbon dioxide limits for new power plants that will set separate standards for coal-fired and natural gas-fired generating units.  The proposed limit for new gas plants is 1,000 pounds per megawatt-hour for new gas units and 1,100 pounds per megawatt-hour for smaller gas plants and new coal plants. New coal plants would be allowed to average their emissions over a seven-year period if they agreed to meet a more stringent standard in a range from 1,000 pounds per megawatt-hour to 1,050 pounds per megawatt-hour. 

This rule is a new proposal, revising an earlier proposal from April 2012, in which the USEPA had intended to set a single standard of 1,000 pounds per megawatt-hour for both coal- and gas-fired plants.  Under the proposal, new power plants would have to install carbon capture and sequestration technologies to comply with the emissions limits outlined for the plants.   Those technologies capture carbon dioxide and bury it underground but requiring use of the technologies has been vigorously opposed by industry user groups, which say they are not feasible yet. 

For more details about this new proposal visit: http://www2.epa.gov/carbon-pollution-standards/2013-proposed-carbon-pollution-standard-new-power-plants. Included are fact sheets, technical sheets, and regulatory impact sheets, along with a link to the previously-proposed 2012 rules for comparison.

This month twelve years ago Nationwide Boiler responded to an emergency call at Ground Zero. The horrific events in New York City on September 11, 2001 left many buildings without heat and other necessary steam-based facilities due to the destruction of the steam delivery infrastructure. The devastation of the area included a 20-inch steam main used for delivery of the steam to users. In order to restore activities around the damaged area of Ground Zero, facilities, including steam delivery, had to be replaced and temporary boilers were required.

Within hours of receiving the go-ahead for the emergency rental, shipping arrangements were made for a complete 140,000 lb/hr steam plant to be installed near the damaged steam main at Ground Zero. A 70,000 lb/hr trailer-mounted rental boiler was dispatched from the Nationwide Boiler East facility in Delanco, NJ, and a self-contained water treatment van and second rental boiler were shipped from the Nationwide Boiler headquarters in Fremont, CA.

Operating on a fast-track basis, the steam plant was delivered, brought on-line and readied for operation at Ground Zero in a matter of days. The system steam main was connected to temporary steam distribution lines, providing offices and residences in the area with heat and the other steam-based services.

If you are in an emergency situation and need temporary steam, Nationwide Boiler’s mobile rental boilers can be shipped immediately, worldwide. Download our emergency preparedness plan and contact us today at 1-800-227-1966.

NEMA enclosures are used in industrial applications to house and protect variable frequency drives and other electrical equipment. Each enclosure has its own rating to designate the type of application for which that particular enclosure was built for; NEMA 3R and NEMA 4X were built for and are most commonly used for outdoor installations. Having an understanding of each enclosure is important when choosing which one is best for your particular application.

NEMA 3R enclosures are generally used for applications such as rooftop air handling units, irrigation pumps, and water/waste-water pumps. They are made from carbon-steel and equipped with white-powder coated paint and fans for temperature regulation. The fans include filters to keep dust, dirt, and insects from entering the enclosure. NEMA 3R enclosures are versatile in the fact that a viewing window can be installed for internal component viewing, and they can be wall-mounted in environments with potential flooding issues. Installation is rather simple and costs are lower than the alternative, but the enclosures are not protected in corrosive environments.

The alternative, NEMA 4X enclosures, are more expensive due to the addition of an air conditioner in place of the fans. However, there are some significant advantages to using the more costly enclosure. NEMA 4X enclosures are stainless steel creating a corrosive-free enclosure, they are equipped with an air conditioner in lieu of fans for better temperature control, and they are the preferred alternative when NEMA 3R cannot be used. Like NEMA 3R enclosures, they can be wall-mounted and a viewing window can be installed, but installation of the enclosure is more complex. The biggest disadvantage of the NEMA 4X enclosure is its high cost; the larger the enclosure the higher the cost, and operation and maintenance can get pricey as well.

Overall, it is crucial to understand the differences between the enclosures to make an informed decision and save money in the long run. For more detailed information on the features of both NEMA enclosures, check out this article from HPAC Engineering Magazine.
