SZL series coal-fired hot water boiler

Introduction of SZL series coal-fired hot water boiler

The SZL series coal-fired boiler is a chain grate water tube boiler designed by ZOZEN Boiler based on advanced international technology and experience. It features a horizontal double-drum and vertical layout structure. The boiler consists of two major parts: the upper part is the heating surface and the lower part is the combustion equipment. The front of the boiler body is surrounded by water-cooled walls. The upper part is connected with drum and the lower part is connected with the header to form the combustion chamber, absorbing the radiation heat of the furnace. At the rear end, a convection tube bundle is arranged between the upper and lower drums. After the fuel is burned in the furnace, the high-temperature flue gas is swept across the convection tube bundle for the secondary return, then guided to a separately arranged economizer and finally enters the dust collector before being discharged through the chimney.

Features of SZL series coal-fired hot water boiler

1. The furnace adopts a close-packed a close-packed arrangement of water wall tubes. The application of close-packed water wall in furnace design changes the traditional structural form of the original industrial boiler furnace water-wall, effectively preventing high-temperature flue gas from scouring and radiating the furnace.

2. Independent water circulation system to ensure the safety and reliability of the boiler water circulation. We have designed independent water circulation systems on the structure, the water circulation structure is simple and clear, the water supply task division is clear, and the cross-sectional area ratio of descending pipe and rising pipe in all areas in guaranteed to be more than 0.4. In the premise that the water quality meets the requirements of the GB standard, it ensures the safety of boiler water circulation.

3. The grate bracket adopts double brackets, the lower channel steel, the upper light rail, the upper heat, the lower force, which has changed the structure of the traditional grate bracket angle steel plus friction bar, the grate bracket is not deformed. The active stocker is operated on the light rail and it is tested in the cold state for 48 hours before leaving the factory.
