As we all know, coal-fired steam boilers are mainly composed of main body, chain grate, front arch, back arch, light furnace wall, steel frame and insulation layer. Its body is composed of a pot shell, a smoke box, a water wall tube, a downcomer, and lower headers on both sides. The tube plate adopts a fully welded structure. The chain grate can be light-weight chain grate, with independent air supply in sections. The steam boiler price is mainly set according to the boiler tonnage, accessories and other processes.

This series of steam boilers has reasonable air distribution and flexible adjustment, which can be adjusted at will according to the combustion conditions. Coal-fired boilers use thicker grate slabs, which have higher strength, longer life of grate slabs and long maintenance cycle. The furnace structure designed with a unique coal combustion theory enables the boiler to have a faster burning speed and an efficient and clean combustion effect, and truly achieve no black smoke emission. In addition, it has a wide range of coal types and can be burned with ⅠⅡⅢ bituminous coal and lean coal.

This series of boilers uses fully welded tube plates, no slack leakage. Large diameter water wall, good water circulation, low water quality requirements. Light furnace wall, light weight, beautiful and generous. Sufficient fuel, good smoke reduction and dust reduction, high thermal efficiency. The steam boiler price is competitive, and the boiler is delivered in the form of integral quick-installation, with an extended structure and sufficient output. Electric control realizes stepless speed regulation of the grate, limit parameter alarm and interlock protection. It has outstanding characteristics and advantages, reasonable structure, and is sold in more than 100 countries and regions in the world, and it has won unanimous praise and trust from customers!

The coal-fired boiler adopts a unique structural design. The coal-fired steam boiler performs furnace flue gas disturbance to ensure complete combustion of volatiles. The air volume accounts for about 30% of the total air volume, and the wind speed is about 50m³/s. Set up an independent secondary fan, the air volume and pressure are easy to control and adjust. The high-temperature flue gas generated by the combustion first enters the eight-shaped flue on both sides of the body from the tail (in this case, it is a water tube type), and the flue gas flows outside the tube. The flue gas cooled by the eight-character flue then enters the threaded tube (fire tube type) arranged in the drum from the front smoke box. Exhaust from the rear smoke box, this design fundamentally solves the problem of tube sheet cracking in a pure fire tube boiler.

The boiler longitudinal and circumferential seam welding adopts advanced submerged arc automatic welding technology to ensure the welding quality. All longitudinal and circumferential welding seams are subjected to 100% radiographic inspection. Its smoke tube and tube sheet are welded by pre-expansion to eliminate the gap between the tube and the tube sheet, and then the welding process of argon arc automatic welding is adopted. Effectively eliminate stress and prolong the service life of the boiler.

The steam boiler price is reasonable, the boiler adopts adiabatic combustion, the combustion efficiency is high, the energy saving is obvious, and the fuel cost is low. This series of boiler products are widely used in schools, textile factories, clothing factories, printing and dyeing factories, restaurants, food factories, beverage factories, soy products factories, meat products factories, canneries, wineries, pharmaceutical factories, packaging factories, building materials factories, coatings Factories, swimming pools and other enterprises and institutions. It is the first choice for small and medium-sized steam users to select boilers. Zozen Boilers specializes in exporting industrial boiler products, and has reached a friendly cooperative relationship with a group of users. Welcome everyone to come and consult!
