Product Description

Technical Description:

SZL type series assembling water pipe steam/ hot water boiler is double-drum boiler water pipe travelling grate boiler. In boiler proper, there are two drums up and down which are arranged along the boiler center. Up drum forepart and two-side water wall tubes compose radiation heating furnace. Economizer is arranged in the back of the boiler, and after high flue gas which produces by burning is absorbed heat in furnace, it comes into convection bank through cooling chamber and sends smoke to chimney to discharge into the atmosphere by draught fan through economizer, dust remover

SZL series horizontal drum steam/ hot water boiler-energy-saving boiler, product features are as follows:

1,After simplifying the water cycle loop, it reduces water cycle resistance, and raise rising tube velocity. For hot water boiler, in its right and left water cooled wall which water cycle flow resistance is strong adds backwater ejector device to improve the reliability of the water cycle, ensure safe and stable operation of boiler.

2,Arrange enough heating surface, which makes the quantity of heat of the fuel set off can be fully heated to transfer to work medium. Flue gas temperature is about 170Dec..

3,Reasonably decorate front and back arch, and improve furnace temperature at the same time, strengthen disturbance of the smoke in the high-temperature region, reduce chemically incomplete combustion heat loss and fly ash loss.

4,Combustion equipment adopts light chain grate stoker. It has features about easy operation, convenient maintenance, stable burning and high thermal efficiency. It achieves mechanical stoking,and equipped with draught fan and blower to realize mechanical ventilation. Adopt loose core chunk of stoker, and ensure has enough efficient fire grate area. Improve the reliability of operation in the stoker, meanwhile, ensure coal burn fully.

5,Convection heating surfaces of the rich is the largest,and efficiency characteristicof boiler operation is stable and has overload capacity at a certain degree. Change convection tube inline pitching to staggered pitching. Improve thermal efficiency through improving heat transfer series, and improve thermal efficiency of boiler.

6,Through taking above measures, thermal efficiency of each specification boiler is more than76%, and is higher than national standard.

7,Adopt downcast double side air, single plenum, and independent control. Burn stably and operate reliably. In the exit of furnace, we set up smoke inertia separation device to make the original discharging dust concentration low pressure is 1800mg/Nm3. Coordinate with efficient water dust scrubber, boiler depuration concentration meets the demands first area in our country and environmental requirements.

8,Compact structure. Apart from 4t/h is fast loading when leaving factory, the rest are n bulk when leaving factory and assemble at the scene. Adopt assembling structure, decrease installation workload at the scene, cut short 2/3 of installation period, and low investment. Stokehold can adopt single-deck arrangement, which can decrease 50% cost of construction of stokehold

9,The diameter of upper drum is increased, which increases steam space, meanwhile, improve separation device of water and steam to ensure steam quality.

10,Water volume is large, and it's benefit for power-off protection, and applicable load change ability is strong. The automatic level of the boiler is high. Boiler water supply automatic adjustment, high-low water alarm, low water level interlock protection, and draught fan or blowers interlock protection.Electrical Cabinets equip with complete automatic control and monitoring instrument. It has high degree of automation. Safe and reliable, and operate easily.
