Example Embodiment

[0030] The present invention will be further explained below in conjunction with specific embodiments and drawings.

[0031] In the process of ship design, the steam consumption of equipment and ship tanks is usually estimated under various working conditions, and the results are used as an important basis for the selection of combined boilers. Generally, ship tanks have two states, namely heat preservation state and heating state, and assuming that the tank is a uniform body, it is considered that the heat emitted to the external medium is proportional to the temperature difference. Therefore, steam consumption does not change under a certain constant load.

[0032] Therefore, the specific steps for calculating the total steam consumption of the ship are as follows:

[0033] Step 1: When the ship's tank is in the heat preservation state, the heat dissipation is equal to the heating, and formula 1:

[0034] ΣKF(T A -T C )=S K (I S -I D )Formula 1

[0035] In formula 1, S K Is the amou...

Abstract

The present invention relates to a method for calculating total ship steam consumption, and belongs to the technical field of ships. The method for calculating total tank steam consumption comprises: firstly calculating tank steam consumption in a heat preservation state; analyzing and solving the tank steam consumption in a heating state by using a calculus method and through a differential equation; and finally taking steam consumption data to multiply an appllication coefficient of a tank, and obtaining the total tank steam consumption. According to the method disclosed by the present invention, a more accurate result of the tank steam consumption in the heating state can be obtained, accuracy for calculating the total ship steam consumption is significantly improved, and a more reliable basis and guarantee are provided for type selection of a ship boiler.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for calculating the total steam consumption of the whole ship. Background technique [0002] At present, conventional ships are equipped with heavy oil tanks, slop oil tanks and other tanks with relatively viscous internal media. These tanks usually need to be heated to work normally, and most ships use saturated steam as the heating medium, and the steam is passed through the exhaust gas. Produced after being heated by a boiler or an oil-fired boiler. Therefore, how much boiler capacity should be configured on the ship depends on the calculation result of the steam consumption of the whole ship. [0003] However, the current calculation method of steam consumption tank heating generally divides the state of the tank into two parts: heat preservation and heating. The calculation of the heat preservation part mainly considers that the heating and heat dissipation are equal...
