cfbc boiler capacity for 251 mw lignite

Boiler tube rupture: 1, you can hear the sound of soda injection time phenomenon (1) of the cfbc boiler capacity for 251 mw lignite burst pipe burst pipes, severe obvious explosions. (2) becomes pressurized combustion furnace by the combustion pressure, and ejecting the smoke and steam from the oven door opening and large air leakage at the furnace walls. (3) water flow is not normal, greater than the steam flow. (4) Although increasing water supply, but is often difficult to maintain the water level, steam pressure and reduced. (5) The exhaust gas temperature decreases, the color of white smoke. (6) furnace temperature is lowered, and even fire. (7) draft fan load increased, the current increased. A bottom (8) has a boiler water to flow out, the wet ash hopper ash. 2, the processing squib boiler (1) are not severely leaking tube rupture and can maintain the water level when the accident is not to expand, maintain the operation load can be reduced for a short time, and then start to be standby furnace shutdown. (2) tube rupture when the water level can not be maintained, should an emergency shutdown, but it should not stop the induced draft fan, Boiler Feed should continue to reduce the wall temperature, the accident will not re-expand. (3) as a result of the boiler when the water shortage, the wall overheat and burst pipes, should an emergency shutdown, and prohibited the boiler feed water, then should withdraw from the furnace over the fire as soon as possible, reducing the furnace temperature, reduce the degree of boiler overheating. (4) if several parallel for the steam boiler, a main steam pipe and the steam should be the parent partition tube boiler accident.

Fast production side economizer spiral finned tube heat exchanger of the high efficiency structure, compared with the conventional light-pipe heat exchanger, the heat transfer area is increased 5-fold, directly enhance the heat transfer rate about five times. Both to meet the energy requirements needed for the operation of the cfbc boiler capacity for 251 mw lignite, but also saves a lot of use of the area.

Installation confusion. In recent years engaged in pressure hot water cfbc boiler capacity for 251 mw lignite installation team more and more complex installation team, installation quality is difficult to control. Select the location and construction of the boiler room is also very confusing, and some have not yet press the "boiler room design specifications" for design and construction.

Recently, we learned that the city of Zhangjiakou Yuxian environment departments to carry out a special investigation of coal-fired cfbc boiler capacity for 251 mw lignites, coal-fired boilers have complete control of the number of the county, painstaking, and practical coal-fired boiler renovation work to ensure safe and stable environment of the area.

The action focuses on the central heating pipe network has access to the dismantling of coal-fired boiler units, still use coal-fired boiler heating key units of 18 coal quality, coal to electricity station uniform implementation of the 1001 residents of coal-fired heating boilers civilian electric boiler furnace demolition and safe usage, the main city of 39 sets of bath boiler operation of treatment facilities, boiler demolished nine agriculture-related enterprises from coal to gas and gas safety carried out a detailed examination. Unit 4 of the use of substandard coal, the filing be investigated according to law, for gas safety problems 9 agribusiness, notify the county Emergency Management Agency and the territorial towns to regulate the management of its duties, to further prevent security incidents from the source .
