Horizontal Coal-fired Boiler Manufacturer

November 27, 2020

Horizontal coal-fired boiler releases heat through the combustion of coal. The heat is first transferred and absorbed by the water cooling wall. The water in the water wall boils and evaporates, generating a large amount of steam. From the top and horizontal flue of the oven, the tail flue absorbs heat from the flue gas by radiation and convection, and transports the superheated steam to the heating apparatus.

SZL type chain grate coal-fired boiler has high efficiency, strong overload capacity and wide adaptability of coal types. It is praised as the high-quality design scheme of contemporary domestic similar products and has the world’s advanced level. The boiler is mainly composed of upper and lower boiler tube, convection tube bundle, water wall tube, drop tube and set box. The upper and lower boiler tube is arranged longitudinally. The combustion equipment adopts chain belt type chain grate and drives by stepless variable speed device. The boiler barrel is equipped with a regular drainage device to ensure the quality of steam. Equipped with continuous automatic water supply device to ensure the safe operation of the boiler, boiler tail arrangement of economizer.

DZL new type water boiler is a new generation boiler that ZOZEN boiler has participated in the development, with enhanced combustion, enhanced heat transfer, water circulation safe and reliable, full output, high efficiency, and output and efficiency for life unchanged. DZL three return boiler is a kind of horizontal, decorate a threaded pipe inside the drum, left and right sides of the chamber of a stove or furnace water wall tube, arch before and after using the new energy saving furnace, using small scales light type chain grate is more advantageous to biomass fuel combustion, equipped with mechanical ventilation fan and induced draft fan, and is equipped with automatic slag machine.

Stone (Vietnam) Co., Ltd. has purchased 3 sets of SZL series high-efficiency and energy-saving chain grate coal-fired steam boilers from ZOZEN Boiler, which not only effectively improved its own capacity and product quality, but also realized the purpose of energy conservation and emission reduction, making it truly achieve green production. ZOZEN SZL series coal fired steam boiler is a double-boiler tube chain grate water tube boiler. Under the grate there are several independent air silos and air regulating devices, which can improve the combustion efficiency of fuel through accurate air distribution and save a lot of fuel cost for the enterprise.

In addition, according to the local environmental protection requirements of Vietnam, ZOZEN also designed a matching dust removal, desulfurization and denitrification equipment for the boiler tail, effectively reducing the emission of NOx. It is worth mentioning that the SZL series coal-fired steam boiler of ZOZEN has a high degree of automation, which can realize the mechanized operation of fuel supply, ash and slag discharging. The reasonable control system can reduce the operation cost and improve the economic benefit of the enterprise under the premise of ensuring the safe operation of the boiler.
