Archived: Code of Practice for management of air emissions from pulp and paper mills: chapter 5

5 Definitions

Biofuel

fuel derived from renewable biological sources (plants or animal waste) such as wood residue, wastewater treatment biosolids or biogas.

Boiler

combustion equipment that transfers thermal energy from the fuel to a heat transfer fluid.

Continuous Emissions Monitoring System (CEMS)

equipment for automated sampling, conditioning or analyzing of emissions from a given source and the recording of data related to those emissions.

Chemical mill

any mill in the pulp and paper sector that operates a recovery boiler or a lime kiln.

Dissolving tank

equipment that collects the smelt from the recovery boiler and dilutes it, usually with water or weak white liquor.

Lime kiln

combustion equipment used to transform calcium carbonate (CaCO ₃) into lime (CaO).

Mechanical mill

any mill in the pulp and paper sector that is not a chemical mill.

Recovery boiler

boiler whose primary fuel is spent pulping liquor and is used to recover the chemical components from the combustion of spent pulping liquor.

Operator

the operator of a pulp and paper mill is an authorized official who:

• in respect of a corporation, is an officer of the corporation who is authorized to act on its behalf;
• in respect of any other person, is that person or a person authorized to act on behalf of that person; and
• in respect of any other entity, is a person authorized to act on its behalf.

Stationary source of combustion

any stationary combustion equipment with a nominal heat capacity greater than 10.5 gigajoules per hour (GJ/h) that operated more than 500 hours in the year where compliance was assessed.

Thermal oxidizer

device used to destroy liquid, solid or gaseous matter through combustion, without recovering the energy produced.

Total particulate matter (TPM)

airborne particulate matter with an upper size limit of approximately 100 micrometre (µm) in aerodynamic equivalent diameter. Only the primary (filterable) portion is considered in this Code of Practice.
