Product Description:
1. The industrial silicon ore blast furnace waste heat boiler consists of a superheater section, an evaporator section, an economizer section, and its ancillary equipment and accessories. industrySilicon ore heatstoveThe waste heat boiler uses the exhaust gas discharged from the industrial silicon smelting furnace to introduce it into the waste heat boiler for heat exchange, producing superheated steam with a pressure of 1.0MPa-2.5MPa, thereby saving fuel and achieving the goal of economy and energy conservation.

2. The heating surface of a waste heat boiler generally consists of three parts: the superheater section, the evaporator section, and the economizer section. According to the heat balance calculation of the waste heat boiler, in order for a single waste heat boiler to achieve maximum steam production, an economizer section must be installed in the waste heat boiler to further absorb the low-level energy in the exhaust gas using feedwater. On the one hand, this can increase the feedwater temperature and steam production of the waste heat boiler, and on the other hand, it can improve the effective utilization rate of the heating surface in the evaporator section.

Product features:
The waste heat boiler adopts a modular structure, and each waste heat boiler consists of five parts: an inlet smoke box, a superheater section, an evaporator section, an economizer section, and an outlet smoke box. The actual production section of the waste heat boiler in the factory needs to be divided into five parts: an inlet smoke box, a superheater section, an evaporator section, an economizer section, and an outlet smoke box, depending on the transportation situation, to facilitate transportation. After being transported to the construction site, it is assembled as a whole.
1. Import and export cigarette boxes:
The inlet and outlet smoke boxes of the waste heat boiler are welded from steel plates. The cigarette box is equipped with lifting plates for lifting and installation. There is an inspection door on the cigarette box for users to enter and inspect.
2. Economizer section:
The economizer section mainly consists of a framework, coil units, inlet and outlet headers, and their accessories. The economizer is mainly used to further absorb the low-level energy of the exhaust gas. On the one hand, it increases the feedwater temperature and ensures the steam production of the waste heat boiler. On the other hand, it can improve the outlet flue gas temperature of the evaporator section and increase the effective utilization rate of the heating surface.
3. Evaporator section:
The evaporator section is mainly composed of a framework, coil groups, inlet and outlet headers, and their accessories, all of which are the main heat exchange sections of the waste heat boiler. After absorbing heat in this section, the working fluid undergoes a phase transition from liquid to vapor-liquid co phase. After steam water separation, it can provide saturated steam to the superheater section.

4. Superheater section:
The superheater section is mainly composed of a framework, coil groups, inlet and outlet headers, and their accessories, all of which are the main heat exchange sections of the waste heat boiler. After absorbing heat in this section, the working fluid produces superheated steam that meets the requirements of steam turbine power generation.

Product advantages:
1. High cost-effectiveness

Due to the use of needle shaped tube heat exchange elements and vertical modular layout structure in this waste heat boiler, the overall investment costs of equipment, installation, and infrastructure construction are greatly reduced under the same heat exchange area. In terms of equipment installation and layout, it provides users withProvided a large space.

2. Self cleaning ash

Due to the cantilever structure of the needle shaped tube, the needle ribs vibrate under the impact of airflow, making it difficult for cigarette ash to accumulate. Combined with the strong turbulent flow of smoke, the needle shaped tube is replacedThermal components have strong self-cleaning ability.
3. Wear resistance

The needle shaped tube is arranged in a straight line, and the needle ribs divide the space into several small areas, which has a uniform flow effect on the airflow. Compared with the light tube, spiral finned tube, etc. that are arranged in a staggered manner, it is more effective in other areasUnder the same conditions, the wear life is high3~4times.

4. Low energy consumption

The needle spacing, tube spacing, and arrangement of needle shaped tubes are important design parameters for waste heat boilers. Regardless of whether the boiler is horizontally or vertically flushing the tube bundle, all needle shaped expansion surfaces are subject to the lateral turbulent flow of the flue gas, and the airflow forms on the back of the cylindrical surface of the needle ribsSymmetrical steady-state vortices and recirculation zones continuously disrupt and regenerate the thermal boundary layer, resulting in thinning of the entire heat transfer boundary layer, reducing thermal resistance, and increasing heat transfer coefficient.

5. Sealed well

All butt welds are welded using argon arc welding, which significantly improves the welding quality compared to manual welding.

6. Lightweight and compact in size

Due to its vertical layout, this device achieves reverse heat exchange between flue gas and water, significantly reducing its volume and weight. The heat transfer area per unit length is large, and the heat transfer area using needle shaped tubes is the same as that of light tubes7-8Double, it's a spiral finned tube1-3Twice.
