Product Description
Technical Description:
SZL series steam boiler is a kind of horizontal, shop-assembled, double-drum,water pipe, travelling grate boiler.There are two drums up and down: steam drum and water drum. The front of steam drum and two-side water tubes wall compose radiation heating surface. The convection tube bundles between the back of steam drum and the whole water drum compose the convection heating surface. The economizer is arranged at the back of the boiler.
Advantage of SZL series horizontal steam boiler:
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 170°C.
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.

Oil-fuel/Gas-fuel horizontal organic heat-carrier boiler
YY(Q)W horizontal oil(gas)-fuel boiler is a kind of forced circulation oil(gas)-fuel organic heat-carrier boiler. The heating surface of this series of boiler is compact. The heating surface consists of inner, (middle) outside disc tubes. The inner ones will be radiantly heated while the middle and the outside ones will form the convection heating surface. The fuel will be burnt in the combustor formed by the disc tubes. And the most heat will be absorbed by the radiant heating surface, then the air of high temperature will enter the convection heating surface to exchange heat. At last, the air and smoke of low temperature will be
Discharged directly to the atmosphere through the chimney.
Features:
1. The heat efficiency is high and the structure is special. The general heat efficiency can reach up to 90%.
2. The horizontal design is easy and convenient to operate.
3. With the disc tubes, the heating surface can be heated fully and the heat load of the tube can be lowered.
This makes the conductive oil safer.
4. The size of the hearth matches the flame. The heat exchange rate is rather high.
5. The control system is accurate and the temperature of the conductive oil can be controlled within ± 1º C.
6. We have the interlock and other feedbacks if there′s any emergency.
