RESOLUTION WAIVING FORMAL BIDDING REQUIREMENTS AND AWARDING CONTRACT
FOR PURCHASE OF MATERIAL FOR UNIT NO.7 ROTARY AIR PREHEATER
PARTIAL BASKET REPLACEMENT
FOR THE CITY OF AMES,IOWA
WHEREAS,Unit No. 7 boiler utilizes an air preheater to capture the heat in the exhaust gas from the boiler
and transfers the heat energy to the incoming combustion air to warm it to the temperature needed for efficient
combustion of the fuels in the boiler; and,
WHEREAS,the rotary air heater is made of multiple baskets filled with sandwiched layers of steel that rotate
between the exhaust and inlet air ducts and,in doing so,transfers the heat energy from the exhaust to the incoming air
needed for combustion of the fuel in the boiler; and,
WHEREAS,over time,the basket material corrodes,deteriorates,and loses thermal efficiency,and the loss
of thermal efficiency results in more fuel consumption and increased costs to the utility; and,
WHEREAS,previous inspections and temperature data indicates that the preheater needs basket replacement;
and,
WHEREAS,now due to the deteriorated condition of the air heater and its impact on the fan system,Unit No.
7 is limited to its operation, and this load restriction also limits the unit's ability to burn refuse-derived fuel; and,
WHEREAS,the rotary air heater on both plant boilers is manufactured by Alstom Power,Inc.,and during the
recent Unit No. 8 spring outage, one row of baskets was replaced on Unit No. 8; and,
WHEREAS,the material was formally bid and awarded to Alstom Power, Inc.,for the amount of$78,500,
and it provided the only responsive bid out of a total of two received; and,
WHEREAS, since Alstom Power was the only responsive bidder for the aforementioned project, staff
contacted the company and inquired on cost and availability of the needed basket components for Unit No. 7; and,
WHEREAS,Alstom provided a price of$75,067 with delivery three weeks after receipt of order; and,
WHEREAS,this work is considered routine maintenance repair and replacement,and it will also reduce the
amount of fuel required and associated air emissions at any given load point.
NOW,THEREFORE,BE IT RESOLVED by the City Council of the City of Ames,Iowa,that waiver of the
purchasing policy requirement for competitive bidding is hereby approved,and a contract is awarded to Alstom Power,
Inc.,of Wellsville,New York,in the amount of$75,067.00 for the purchase of material for the Unit No. 7 Rotary Air
Preheater Partial Basket Replacement
