STACK TESTING (CHP)

The emissions testing company will determine the mass flow of the stack flue gas by using a Pitot Tube to take transverse measurements of the gas velocity in the duct as well as measure the gas temperature and then calculate the Mass Flow. They will also determine the O2 and CO2 content by measurement.

The mass flow of the Gasification Air (sometimes called Primary Air) and Oxidation Air (sometimes called Secondary Air) is determined from the readings on the HMI as measured by the flow meters. The O2 content of the Gasification Air is also noted. The Oxidation Air content is just normal air (I.e.: 21%)

The fuel analyses determines the heating value of the fuel. The moisture content of the actual fuel is measured by testing it at the time of the test. (An accurate reading of the moisture content of the fuel is important.)

The net steam energy produced is calculated and noted during the test.

Use standard calculations to determine the mass of the fuel that was used to arrive at the measured results. The calculations are available in the “Steam” reference book.

One week prior to gasifier light‐off we require a delivery of 4 trucks to fill each fuel bin.

After light‐off we require half of the capacity shown in the table below.

Start Date for Fuel Deliveries: Full capacity deliveries to commence approximately one week after gasifier light‐off as per table below.

Anticipated Monthly Consumption:

% Moisture Lb/hr US tons/hr US tons/mo 10 4,673 2.34 1685 40 7,602 3.80 2736 55 11,606 5.80 4176 Assuming system runs 24/7 at design load.

Consumption of fuel will vary with steam demand and electrical consumption.

Site Storage Capacity: 285 tons Desired Delivery Frequency: Unknown – 5 to 6 trucks daily (M – F)

Truck scales are not available on‐site.

Special requirements for fuel delivery: Delivery will entail a route entering the service road off of Dickman Road. More information will be given once a contract is awarded.

Manufacturer’s fuel specifications:

NEXTERRA FUEL SPECIFICATIONS

The Battle Creek CHP System will operate on the fuel defined as “clean wood chips”. Wood chips are typically 2 ¼ x 2 ¼ x ¼ inch, are delivered in a consistent size range, and have very little ash content. The System is designed to operate on fuel conforming to the following specifications (which allows a much broader range of wood fuel to be used than the specified “clean wood chips”):

Fuel Size Wood residue must be sized to 3 inches minus in all dimensions. Long fibers or sticks that are longer than 3 inches in length are not acceptable. Residues sized less than 1/4 in. must be limited to 25 percent or less.

Fuel Composition Wood residue must be a clean fresh mix free of substances foreign to natural composition of wood such as preserving chemicals, paint, processing chemicals, glues, sulphurous, phosphorous or nitrogenous chemicals that might be classified as hazardous or appear in flue gas or ash. The fuel should be free of nails or other metal strips.

The wood fuel should be free of rotten material which evidences a state of decomposition. The wood fuel should be free of leafy greens or needles.

Fuel must be well mixed with a consistent moisture content level. The System will be able to accommodate seasonal fluctuations in fuel moisture content.

Ultimate and Proximate Analysis The proximate and ultimate analysis of the design fuel on a dry weight basis for performance calculations is as follows:

Proximate Analysis Ultimate Analysis Component Component Moisture Content (wet basis) 10‐55% Carbon 48‐52% Volatile Content 70‐85% Hydrogen 5‐6% Fixed Carbon 15‐25% Oxygen 36‐44% Ash <10% Nitrogen <0.2% Higher Heating Value (HHV) > 8500 btu/lb Sulphur <0.025% Chlorine <0.025% Total 100%

Ash Content Wood fuel shall contain less than 10% dry basis inorganic material including materials that are part of the normal composition of wood as well as materials that are not part of the makeup of natural wood. The initial deformation temperature (IDT) of ash must be greater than 2100° F.
