Tomato season is here, and we already have a 70,000 lb/hr, 400 psi design trailer-mounted rental boiler on location at one of our customer sites to support peak season steam demand. This boiler is rented annually in the Central Valley of California for three to four months during the tomato processor’s short but critical production season. To meet the requirement of 5 ppm NOx, the boiler is supplied with an ultra-low NOx CataStak SCR System. This solution allows the facility to operate their own boilers without overworking them, while complying with local air regulations and satisfying seasonal demand.

Some years ago, the company identified a bottleneck in its evaporation system that hindered peak production capacities. The bottleneck was easily resolved; however, it would take more steam to fully realize the increase in production. Although the existing boilers were capable of running the newly found evaporation capacity, the increased production required the existing boilers to operate at 100% output continuously, leaving no room for margin and no buffer against any process anomalies. After evaluating the cost of investing in a new boiler, the detrimental effects of operating the existing boilers at 100 percent output, and the process vulnerabilities of having no excess steam capacity, the decision was made to rent a supplementary steam boiler on an annual basis.  

Many industries face periods of increased process steam requirements and to satisfy demand, steam can be supplemented with a temporary rental boiler. This practical solution allows facilities to maximize the resources needed to meet current, short-term and long-term steam needs. A short-term or long-term rental solution can save time, conserve capital, minimize risk and maximize available resources.

Promoting a sustainable future is the focus now more than ever in the boiler industry, and Nationwide Boiler has been at the forefront of identifying and supplying reliable ultra-low NOx solutions to industry for more than three decades. Today, we can proudly state that we have achieved 5 ppm NOx performance with a recent ultra-low NOx burner/boiler package - and the outlook is bright for this ultra low NOx burner. 

With half of the state covered in forests, it is no surprise that Washington is one of the country's largest lumber and plywood producers. Exterior Wood is a leader in the industry for pressure treated wood products and is in the same business park as Nationwide Control Solutions, a division of Nationwide Boiler Inc. Facing operational issues with their existing 700 HP CB boiler, Exterior Wood consulted Nationwide Control Solutions to evaluate their system and recommend the best solution to address each of the problem areas.

The problem areas that were identified included: (1) the burner head assembly constantly getting burnt out and replaced, (2) the combustion air fan motor which was rebuilt many times without a like-in-kind replacement option, and (3) stack temperatures at low fire were so low that the stack gases would condense in the stack and rain down corrosive condensate on the boiler tubes. Plus, the boiler tuning was becoming increasingly difficult to meet their local emissions requirements due to the age and condition of the existing burner controls. After a thorough review of existing equipment, site conditions, and natural gas usage reports, we concluded that the boiler was greatly oversized and that continuing to replace and rebuild components was not a viable solution for the longevity of the system.

Based on these results, our team offered a new 250 HP Superior package firetube boiler with an Oilon LN30 ultra-low NOx burner that was capable of not just meeting but exceeding their NOx emissions requirements of 12 ppm. Upon start-up and source testing, the ultra-low NOx capabilities of the Oilon burner were proven with the impressive results of 5 ppm NOx and 0 ppm CO output. Plus, the LN30 recently completed additional testing on a boiler from Nationwide's stock inventory, with results that prove it to be a reliable 2.5 ppm option.

Built upon cutting-edge technology, this new Superior Boiler/Oilon burner package will provide Taiga / Exterior Wood with many years of low maintenance and reliable operation. And, with a commitment to sustainability and efficiency, this solution ensures future emissions compliance to help minimize environmental impact.
