In the accident investigation process, the reasons for low pressure boiler thermal efficiency explosion, nothing less than three points: gas (fuel), air and heat. Once the three reaches a certain level, causing the boiler exploded not far.
Low nitrogen low pressure boiler thermal efficiency technology made a major breakthrough, however gratifying that through the unremitting efforts of domestic boiler companies, China's low-NOx combustion technology gradually into the world advanced list, catch up with a lot of foreign advanced technology.
What are the characteristics of the low pressure boiler thermal efficiency? 1, the automatic control of the boiler pressure controller, tracking, on the feed pump may be electrically heated tube automatic start and stop control when the load changes, may be manually controlled. With a number of complete protection, leakage protection, water protection, ground fault protection, overcurrent protection, what are the characteristics? Boiler automatic protection, safe home. 2, automatic intelligent control techniques, without staff on duty. Flexible work can be set to manual or automatic mode. There are 3 boiler, automatic operation may be set as required boiler period, one day may be provided a plurality of different working periods, so that each heating boiler starts automatically sharing group, the group switching cycle heating, the respective contact time, the same frequency improve equipment life.
Heat loss Q5The main factors affecting Q5 are low pressure boiler thermal efficiency capacity and external area of furnace body, water wall and furnace wall structure, ambient air temperature and air flow condition, boiler load variation, etc. The main factors affecting Q5 are boiler capacity and external area of furnace body, water cooling wall and furnace wall structure. Generally speaking, the larger the boiler capacity, the larger the surface area, thus the greater the absolute value of heat loss. However, according to the percentage of heat loss, when the boiler capacity increases, the fuel consumption increases in a positive proportion, while the surface area and furnace temperature of the boiler do not increase in proportion with the increase of the boiler capacity. In this way, the corresponding unit evaporation surface area is reduced, so the larger the boiler capacity, the smaller the heat loss. If water wall and furnace The wall structure is tight and compact, the heat preservation is good, the air temperature around the boiler is high and the flow is slow, the heat dissipation loss is small.
At this time, the heat transfer efficiency of the boiler will be greatly reduced and the incomplete combustion loss will increase. Therefore, reasonable control of the air-fuel ratio, as far as possible to reduce exhaust heat loss and incomplete combustion loss, is another way to improve the thermal efficiency of boilers.Read More
2020-4-5 · Ocean thermal energy conversion (OTEC). OTEC is very sophisticated heat engine that uses the temperature difference between cooler deep and warmer surface seawaters to run a low-pressure turbine. Since the temperature difference is low, about 20°C, its thermal efficiency is also very low, about 3%.; In modern nuclear power plants the overall thermal efficiency is about one-third (33%), soRead More

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.Read More
