1. A 30 MW unit is equipped with 130 tonnes, which is a relatively common configuration. Two units are two high temperature and high pressure boilers of 130 t/h. The principle of this configuration is that the unit is pure condensing and does not require external heating, and all the steam is used to produce electricity. If heating is required (counter-pressure machine or condensing machine), the evaporation capacity of the boiler must be greater.
Although the higher the setting (pressure temperature), the lower the amount of steam required, the difference is not too great.
Our factory previously had two 25 MW medium temperature and medium pressure units, equipped with two 130 t/h boilers, which means that the water consumption per hour is 130 tons*2 . This is treated (pure) desalinated water. water), no industrial water for cooling equipmentis lying.
2. Power plant boilers are all steam boilers, and hot water cannot produce electricity (hydropower is another matter). Discharge volume and leakage volume are usually considered in the design. No more than 10% of impressions are completed.
3. Hot water boilers are generally small and are used in some civil industry applications, such as hotels, public baths, small factories requiring hot water for heating, chemical plants, etc. Hot water boilers are usually expressed in terms of power, which facilitates a direct understanding of heat consumption (amount of coal), while steam boilers are usually expressed in terms of evaporation, e.g. 130 t/ h.
