The Ohio Environmental Protection Agency on May 11 issued a final permit-to-install (PTI) to Cleveland Thermal LLC for the installation of two 182.0 mmBtu/hr natural gas-fired Hamilton boilers (emissions units B009 and B010) at the Hamilton Avenue facility in Cleveland.
The new units are:
- B009 – Natural gas fired boiler rated at 150,000 lbs steam per hour and 182 MMBtu/hr heat input equipped with Low NOx Burners (LNB) and Flue Gas Recirculation (FGR); and
- B010 – Natural gas fired boiler rated at 150,000 lbs steam per hour and 182 MMBtu/hr heat input equipped with LNB and FGR.
The natural gas-fired boilers are to be equipped with LNB and FGR equipment that is designed to meet a NOx emission rate of 30 ppmv dry basis, corrected to 3% oxygen and 0.036 lb/mmBtu which satisfies the BAT source design characteristic requirement. This is based on the boiler manufacturer’s information submitted as part of the permittee’s application for a permit to install.
Notable is that the U.S. EPA last year worked out a clean-air legal settlement with Cleveland Thermal covering both the Hamilton Avenue and Canal Road facilities that included “New Natural Gas Boilers” with a total capacity of no less than 364,000 mmBTU/lb of steam that Cleveland Thermal is required to install at the Hamilton Avenue site.
Said the company website about these operations: “Cleveland Thermal serves its clients from two plants: one located on Canal Road near the city’s Flats District and its Hamilton Avenue location on the bluffs, just east of Downtown Cleveland. Cleveland Thermal’s pipeline consists of nearly 20 miles of piping that transports energy from either of these facilities to your building. In fact, Cleveland Thermal’s underground piping network serves more than 30 million square feet of property. From both of its facilities, Cleveland Thermal puts out 1.25 billion pounds of steam and 18 million tons-hour of chilled water annually and is expanding to meet growing demand.
“The Canal Road plant has the capacity to generate more than 450,000 pounds per hour of 150 psig steam for distribution. This facility serves as Cleveland Thermal’s main source for providing heating to its customers. The Hamilton Avenue plant serves as Cleveland Thermal’s chilled water plant and has 12,000 tons of cooling capacity. Its district chilled water infrastructure was designed as a ‘closed loop system.’ This means that the water is cooled down to approximately 40° for a continuous supply to the central business district.”
