Supper-charged Boiler Experiment Bench


Supper-charged Boiler Experiment Bench

The supper-charged boiler experiment bench is used to simulate the marine steam-powered propulsion system and steam supply system.

1. Composition and Working Principle of Test Bench

The experiment bench includes nine parts: pilot supper-charged boiler, air supply and exhausted flue gas system, oil supply system, steam accumulator system, bypass recirculation system, pilot steam turbine, condensation water supply system, steam system and control system. Oil supply system provides fuel oil to supper-charged boiler. The water in boiler is heated to generate steam by absorbing the combustion heat of fuel, and then the steam is supplied to steam turbine or steam reservoir system. After doing work, the steam is condensed into water and then is fed into the boiler again. Thus, the experimental verification of steam propulsion and steam supply is completed.

2. Function and Performance of Test Bench

The various validation evaluation experiments, such as steam propulsion simulation experiment, the operating mode experiment in the steam supply system, the control strategy experiment in the steam supply system, propulsion in coordination with steam supply experiment etc., can be carried out by applying this experiment bench. The supper-charged boiler experiment bench is the first and only one in China, and the technical performance can reach the international advanced level.

3. Achievements and Applications

Up to now, we have undertaken several naval pre-research projects, 863 program projects and the projects of National Natural Science Foundation of China. The relevant projects of 701-research Institute and the 703-research Institute of China Shipbuilding Industry Corporation have been tested and evaluated. We published three papers searched by SCI citation index, obtained three invention patents, and won the second prize of national science and technology progress once, the first prize of national defense science and technology once, the second prize of national defense science and technology once.
