FIELD: production of steam; steam boiler separators. SUBSTANCE: feed water is fed to drum-type boiler via distributing device from two sides; circulating water is fed smoothly over entire length of drum-type boiler via receiving box excluding drop priming, thus preventing hydraulic impact and appearance of swinging wave. Taking the salts with blowdown water is effected from the area where saturation with salts is maximum (150 to 200 mm above bottom) over entire length of boiler; ratio of boiler diameter to its length is 1:3 to 4. EFFECT: enhanced reliability and operational efficiency due to optimization of methods of delivery of circulating and feed water, taking and carrying the salts with blowdown water and change in relationship of boiler diameter to its length. 3 cl, 2 dwg
