1. Marine Hot Well Unit Description

    This series hot well is one of the most important parts of the combination systems of fuel-oil exhaust gas and boiler. The main use of hot well is to cooling the steam to water, which is the medium after the function of the internal cycle of exhaust gas boiler. The water is also used for the continue cycle of the system and at the same time it is useful to economize the fresh water and the remaining hot cycling. During the cycling system the medium would be inevitably polluted by oil and other impurities. At one time, hot well is also the filter instrument of the working medium of the cycling system. After the medium filtered through hot well cooled water, the oil and other impurities was separated, then drowned to the bottom of the cabin of the ship.

    Hot well unit consists of 3 parts. These 3 parts respectively are the atmosphere condenser, the condensing water receive cupboard and the save cupboard (hot well).

2. Principle of Marine Hot Well Unit

    The steam and condensing water which come from condensing water pipe was cooled by atmosphere condenser,then the condensing water get into the condensing water receive cupboard. The cooling water come from sea pressure tank, enter the cycling of cooling chamber and flow out from cooling water outlet. The filters of the condensing water cupboard filters out the larger particles, the floating oil is separated from the water through the specific gravity difference of oil and water, observe the water from the sight mirror, open the valve to discharge oil when the oil reached the thickness. The cooling water inflow the save cupboard and then discharge from the drain outlet. 

    Adding fresh water to the save cupboard by automatic supply water inlet or manual operation supply water inlet. If the water temperature is too low, heating the water by high temperature steam, then pumping the water to boiler for reused after the water temperature reach the requirement. If the water level of the save cupboard is too low, the boiler feed water pump stop automatically.

3. Marine Hot Well Unit System Composition

    Hot well unit module is composed with public base, marine atmosphere condenser, condensate-water observation cabinet, hot-water well, automatic replenish-water valve, thermometer, temperature controller, liquid controller, hot-water pump, valve and etc. The hot well unit is constituted part of steam condensate-water closed loop circulatory system. The surplus steam produced by boiler and condensate- water produced when the steam passing through the steam-using devices, they are cooled when passing through atmosphere condenser, then flow into hot-well, hot-water filtered in hot-well, exhausting the oil and dirty, sending it into boiler by pressure-increasing pump of boiler supply water, supply to continue circulatory in system, accomplishing heat-exchange of the whole system.
