difference between heat recovery steam generators

Some people say that is a kind of difference between heat recovery steam generators boilers; It was also said boiler is a boiler, steam generator, steam generator, the two are not the same kind of device. Well, this is really both the same kind of product? If yes, what kind of different but both do?

Burns Hospital Affiliated Hospital of Shanxi Linfen Linfen Steel is attending a hospital burns burns and other diseases. Hot water boiler is essential hospital equipment heat, hot water output can provide disinfection of medical instruments and ward heating demand. With constantly improving our environmental policy, boiler correspondingly introduced more sophisticated Use. Linfen hospital burns to respond positively to the national environmental policy, decided to introduce an environmentally friendly low nitrogen gas hot water boiler. Taking into account the special circumstances of the hospital, the boiler should also have the use of safe, clean overall characteristics. Based on the above considerations, finalize the Linfen hospital with burns boiler party cooperation fast, fast is provided by one side of a gas condensing pressure hot water boiler (CWNS2.1-95 / 70-Y.Q).

How steam boiler and steam turbine cycle and constitute the weight of steel: steam boiler, the following is a question and answer form, to learn the boiler-related knowledge, understanding and a way to continue to progress in their learning on the road, and at the same time , we can continue to add their own expertise in this area. Thus, to achieve the proper use and rational use of the boiler, get good economic returns. 1. Move the steam boiler, it needs to record it? Mobile steam boiler, whether required to be recorded, to see whether it is greater than the boiler pressure 0.1MPa, and, if its capacity is greater than 0.25 cubic meters. So, on this issue, we can not give a specific answer, because they do not know these two particular aspects. In addition, we also need to know is whether the steam boiler needs for the record, not to see it is fixed or mobile, is to look at the pressure and volume of these two parameters. 2. The power plant, the steam boiler and turbine, how to form a loop to cycle power generation? Power plants, boilers and the steam turbine cycle is configured, for: first steam boiler to generate steam, and steam to the steam turbine. By rotating the steam turbine to drive generators. Thereafter, the exhaust gas turbine into the cold end of the condenser device, and condenses into water. In addition, the feed pump is fed by the condensate pump, then re-entering the boiler. Thus, a loop may be formed, and further, to achieve cycle power generation.

Types of horizontal boilers in Chemical Engineering

A horizontal boiler is a device to generate steam with heat up water or any liquid as desired. It is also known as steam generator because it main purpose is to generate steam by heating water at low to medium pressure. A horizontal boiler is a closed container made of steel or alloy steel and brass can be used for horizontal boiler material but it must be a live steam model.
