Recovery boiler is the part of kraft process of pulping where chemicals for white liquor are recovered and reformed from black liquor, which contains lignin from previously processed wood. The black liquor is burned, generating heat, which is usually used in the process of making electricity, much as in a conventional steam power plant .
The black liquor is an aqueous solution of lignin residues, hemicellulose, and the inorganic chemicals used in the process. The black liquor comprises 15% solids by weight of which two thirds are organic chemicals and the remainder are inorganic. [3] Normally the organics in black liquor are 40-45% soaps, [4] 35-45% lignin and 10-15% other ...
During the period from 1988, Chemrec developed two pilot plants for first-generation atmospheric air-blown BLG gasifiers, first 1988–1989 with 3 tds/d (ton black liquor solids per day) capacity at SKF, Hofors, Sweden, then 1990–1994 with 75 tds/d capacity at AssiDomän, Frövi, Sweden, and followed by scale-up to the first commercial demo-plant, with this technology and 330 tds/d capacity ...

Men who had high alcohol intake (defined as 15 or more drinks per week) were 33% more likely to develop heart disease compared with men who had moderate intake, or three to 14 drinks a week.
Per the American Heart Association (AHA), alcohol is one of the leading causes of dilated cardiomyopathy. [2] However, multiple longitudinal studies have shown a paradoxical lowering of dilated cardiomyopathy with modest-to-moderate alcohol consumption. [2] ACM is a type of heart disease that occurs due to chronic alcohol consumption.
Alcohol septal ablation (ASA) is a minimally invasive heart procedure to treat hypertrophic cardiomyopathy (HCM). [1]It is a percutaneous, minimally invasive procedure performed by an interventional cardiologist to relieve symptoms and improve functional status in eligible patients with severely symptomatic HCM who meet strict clinical, anatomic and physiologic selection criteria.
Compared to lifetime abstainers, alcohol users had higher blood sugar (2 mg/dl), blood pressure (2 mm Hg) levels, and the HDL-C levels (2 mg/dl) and significantly higher tobacco use (63% vs. 21%). Asian Indians who consume alcohol had a 60% higher risk of heart attack which was greater with local spirits (80%) than branded spirits (50%). [54]
