DZL series boiler has outstanding performance advantages, reasonable overall design, energy saving and environmental protection, and is one of the best-selling products in the market. The coal fired boiler manufacturer produces this series of steam boilers mainly adopts high-efficiency heat transfer elements, i.e. threaded flue tubes, reasonably arranged heating surface and combustion equipment, so that the boiler thermal efficiency is higher than the prescribed standard. Smoke speed design is reasonable, no ash accumulation and wear on the heating surface. It can keep high efficiency, full load, safe and stable operation for a long time.
In the design and manufacture of coal fired steam boiler, the arch-shaped tube plate is reasonably used, and the threaded tube makes the boiler shell change from quasi-rigid to quasi-elastomer. Combined with the wing flue, it completely avoids the cracking of high-temperature tube plates of traditional fire-tube boilers. The use of reasonable water circulation circuit and unique return water injection device improves the water velocity of the riser and avoids water-cooled wall explosion. Adopting energy-saving and strong radiant furnace arch, which has stable combustion and saves coal. Adopting inertial separation of smoke and dust in the furnace, together with high-efficiency dust collector, the smoke and dust emission reaches the requirement of first-class zone.
Coal fired boiler manufacturer with rich experience, boiler production in more than 100 countries and regions around the world, has been trusted by customers. Coal-fired steam boiler compact structure, the boiler below 20 tons can be arranged in a single layer, using a three-return structure, the boiler heating surface is sufficient, softening water space is larger, safe water consumption greater level range, load regulation ability.
DZL series coal-fired steam boiler wall adopts one layer of refractory bricks, two layers of insulation and closed metal cover. In addition, the convenience of operation, overhaul and maintenance should be fully considered in the design, and reasonable devices should be set, such as opening the front and rear smoke box doors for cleaning and maintenance of the flue pipe; the manhole at the top of the pot and the inspection hole in front of the pot are used to inspect the inside of the pot. The platform escalator is set up to facilitate the operation of the furnace. The boiler control system also has automatic water supply function, which can complete various safety protection and alarm.
This series of industrial boilers all adopt zoned air supply light chain grate, with small air leakage, simple and reliable adjustment, which can better regulate the combustion conditions of the boiler and ensure stable combustion of the boiler. The boiler is a full quick-assembly type, the boiler structure is compact, small footprint, short installation cycle, the boiler transported to the installation site, as long as the necessary piping and flue installation can be quickly put into operation.
Coal fired steam boilers produced by coal fired boiler manufacturers can be used for steam required in the production process of industrial products such as textiles, printing and dyeing, paper, plastics, food, etc. It can also be used for steam and hot water heating for industrial production. Daily life in factories, institutions, schools, agencies, etc. for heating, bathing and steaming. ZOZEN Boiler products specializing in the production of various types of high quality boilers and pressure vessels, over the years to provide many users with quality boiler solutions, and get the unanimous praise of customers, welcome to consult.
