fire tube boiler experiment

Please emergency shutdown following conditions: relative to the normal shutdown, emergency shutdown of the fire tube boiler experiment, said boiler abnormalities that, if not stopped immediately, it may cause some economic losses. Therefore, in the following conditions are met that should attract immediate attention, emergency shutdown operation.

Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of fire tube boiler experiment welds is more guaranteed.

Small steps in the installation of fire tube boiler experiment parts: the main part of a small boiler for the body, chimney, sub-cylinder, water pumps, then its component mounting step is what is it? Here's to give you the specific introduction:

To prevent accidents, but also carry out regular inspection of fire tube boiler experiments, including external inspection, internal inspection and hydrostatic testing, inspection cycle boiler has the following requirements: First, the frequency of testing under normal circumstances, in general for an external boiler per year inspection, internal inspection every two years, a power generation boiler system can be appropriately adjusted in accordance with the overhaul cycle power plant, the boiler can not be performed for the internal inspection, hydrostatic testing once every three years, when the internal test and external test with at the time of the year, we should first conduct internal testing, and then to external inspection. When reassembling the boiler began to put into operation, the boiler stops running when you need to recover more than one year to run, combustion and boiler safety automation system with changes: two, external inspection under certain circumstances, when any of the following circumstances, should also be external inspection . Third, the internal inspection in a particular situation: In addition to general internal inspection of boilers when any of the following circumstances, should also be an internal inspection: before reassembling the boiler put into operation, the boiler needs to stop more than a year before returning to run, steam boilers pressure components by major repair or renovation and re-run after one year after the hot water boiler pressure parts through the major repair or renovation and re-run after a year later, according to the operation of boilers, steam boilers but also according to the results of previous internal inspection , I have doubts about the safety equipment reliability. In addition, after the boiler accident, to conduct an internal examination under impact of the accident on the safety performance of the equipment, to determine whether internal inspection. Fourth, the hydrostatic test under certain circumstances, in addition to the general six years to conduct a pressure test, the boiler pressure parts after major repairs or transformation, but also the need for the boiler pressure test. ;

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes
