Brass nozzle SPB series

FEATURES • Variable capacity hollow cone spray nozzles generating fine atomization with uniform spray distribution. • Spray capacity can be controlled by only adjusting return pressure while supply pressure kept constant. Spray capacity becomes maximized by fully closing return value and minimized by fully opening return valve. The turndown ratio of spray capacity is 1:10. • A part of supplied liquid is flowed back when return valve is open and supply flow increases. The increase of supply flow is within 40% of the maximum spray capacity. • The variation in droplet size of the spray can be minimized despite the modulation of spray flow. SPB series nozzles are suitable for evaporative cooling in cooling towers where the inlet gas temperature varies. MATERIALS • Stainless steel APPLICATIONS • Temporary exhaust gas cooling in incinerator • Moisture control of exhaust gas in rotary kiln • Exhaust gas cooling in furnace MAIN INDUSTRIES • Pollution Control • Iron and Steel • Paper and Pulp • Ceramic • Chemical
