    "body_text": "Researchers mixed bituminous coal with one to 10 percent industrial organic cleaning wastewater and heated samples under controlled thermogravimetric conditions. One to five percent blends lowered ignition temperature at low heating rates, and five percent reduced modeled average activation energy from 131.68 to 115.92 kilojoules per mole. At 10 percent, moisture, ash, and diffusion resistance delayed burnout. The laboratory combustion study supplies engineering data, not a field-scale disposal approval or emissions assessment.",
