Beihai Shipbuilding Heavy Industry received an order for 400,000 tons of ore ship cabin energy-saving system

The shipyard cabin energy-saving system project team independently completed research and development, simulation calculation, testing, quotation and customized services. Based on the ship's leading ship design experience, it visited the shipyard and shipping company through a large amount of data analysis. The project team takes the customer's needs as the research and development guide

To analyze the needs of customers in the construction and operation of multiple links, summarize key points, and absorb into product development.

In the development process of one and a half years, the project team compared a number of scheme technologies and carried out a large number of CFD simulation calculations. With the cooperation of Jiangxi Navigation Instrument Co., Ltd., through the comparative experiments under more than 10 severe cold conditions, the actual products were finally obtained. Technical solution -

A heat exchange box based on a forced mixing heat exchange of a sleeve type. The project team obtained a number of patent certificates such as “the ship's fuel preheating system for forced convection heat transfer” and formed a product with completely independent intellectual property rights. This technical feature is outstanding, and it is significantly ahead of the international

Class products have filled the gap in domestic technology.

Li Lu, the person in charge of the project, said: At present, the technical scheme adopted for heating fuel tanks of ships is mainly heating of the whole cabin, and the heating medium is mainly steam. In the winter conditions with the largest steam consumption, the fuel tank consumes a large amount of steam and increases the fuel consumption of the oil boiler.

Consumption. The development of the energy-saving system of the tanker has solved this problem well and made a certain contribution to energy saving and emission reduction.

At the same time, the energy-saving technology of the cabin also brings some advantages. The high temperature corrosion of the bulkhead steel plate can be greatly reduced, and the problem of insufficient steam volume of the exhaust gas boiler after the main power reduction operation is solved. Compared with the existing technology on the market, this product can reduce the use of steel plates,

Reduce high-temperature fuel loss, increase the stability of pumped fuel oil temperature, reduce the configuration of the pump, and the control mode is simple and easy to operate.

In recent years, the shipyard has actively promoted the industrialization of science and technology. The young and middle-aged engineers have been brave enough to expand the territory in the field of ship industrialization. The fan-shaped ducts have been installed in nearly 50 sets of ships; the first system of energy-saving hub caps has been delivered; the loading computer and propeller design The project has advanced rapidly.
