For the purposes of this Chapter, the following definitions shall apply:
(a) "ASTM" means the American Society for Testing Materials.
(b) "Combustion device" means any furnace, incinerator, refuse-burning equipment, boiler, apparatus, device, mechanism, stack, chimney or structure used for burning of fuel or other combustible material or for the emission of products of combustion or used in connection with processes which generate heat and may emit products of combustion. It does not include process furnaces and stills.
(c) "Dust" means gas-borne or air-borne particles and includes fly-ash.
(d) "Dust-separating equipment" means any device for separating dust from the gas medium in which it is carried.
(e) "Fly-ash" is included in the definition of dust in subsection (c) herein.
(f) "Fumes" mean gases or vapors that are of such character as to create an unclean, destructive, offensive or unhealthful condition.
(g) "Grate'' means the surface on which fuel is supported and burned and through which air for combustion is passed.
(h) "Heating or low pressure boilers'' mean all boilers carrying fifteen pounds (15 lbs.) or less steam pressure.
(i) "Incinerator" means a device intended, or used, for the destruction of garbage or other combustible refuse by burning.
(j) "Internal combustion engine" means an engine in which combustion of a gaseous liquid or pulverized solid fuel takes place within one or more cylinders.
(k) "Mechanically fired apparatus" means a combustion device in which fuel is introduced into the combustion chamber by driven mechanical equipment.
(l) "Open fire" means a fire from which the products of combustion are emitted directly into the open air without passing through a "stack or chimney.
(m) "Power boilers" mean all boilers carrying pressure greater than fifteen pounds (15 lbs.) per square inch.
(n) "Process furnaces and stills" mean furnaces, other than boiler furnaces or warm air heating furnaces, used in a manufacturing process.
(o) "Ringelmann Smoke Chart" means the Ringelmann Chart with instructions for use as published by the U.S. Bureau of Mines, 1945.
(p) "Smokeless coal" means coal conforming to the limitations specified by the American Society for Testing Materials for low volatile bituminous coal on a mineral-matter-free basis (ASTM Spec. No. D-388-38T) containing namely, seventy-eight percent (78%) or more but less than eighty-six percent (86%) of fixed carbon, and thirty-three percent (33%) or less, but more than fourteen percent (14%) of volatile matter, both on a dry basis.
(q) "Soot" means agglomerated particles consisting mainly of carbonaceous material.
(r) "Stack or chimney" means a flue, conduit or opening arranged to conduct products of combustion to the open air.
(s) "Volatile" means the gaseous constituents of solid fuels as determined by the procedure defined in ASTM Spec. No. D-121-30.
