once through boiler for hospital

Second, the treatment of once through boiler for hospital safety valve trouble

1, when the safety door normally not automatically start, immediately forced open the security door, the door is opened to exhaust air, while reducing the thermal load of the boiler, reducing the steam pressure;

2, when the back seat is not safe door function, should be forced back seat, if the seat back mandatory security gate pulse invalid pulse should exhaust valve closing, so the seat back;

3, when all the safety door failure or serious over-pressure boiler, the boiler should be stopped immediately, can not continue to run down;

Boiler common sense: in the course of the once through boiler for hospital, you will encounter a variety of issues, let Henan Square quick steam boiler manufacturer small series for you to summarize the common sense of the boiler. 1, a positive balance boiler efficiency calculation method, the combustion process, boiler heat losses have? Heat losses, loss of incomplete combustion chemical, mechanical loss of incomplete combustion, heat loss, physical heat loss ash. 2. Effect of type of fuel combustion in the boiler main factors affect the particle size and particle size distribution, affect the fluidization velocity thereof, amount of material to circulation, the influence of the excess air ratio, the influence of the dense phase bed temperature region. 3, the basic form of the heat transfer in the heat transfer process, there are three basic ways: heat transfer and thermal radiation heat transfer and convection. 4, sewage, drainage pipe which sewers:? Drum discharge valve (about) accidental discharge valve before the discharge valve manifold, the exhaust manifold valve manifold drain valve left and right manifold drain valve, water-cooled jacket a discharge valve (approximately) leg discharge valve. Drains: low temperature superheater inlet header pipes, the drain pipe header before and after the cooler, the high-temperature superheater inlet / outlet header pipes, drains distribution header. 5, are connected with the Drum What pipe? Meter and accessories? Superheater tubes, economizer recirculation pipe, platoon expansion tube, condenser tubes, soot blower tube, economizer inlet pipe, the accident put water, concentrated downcomer platoon expansion, a water level gauge, a thermometer, a security door, pressure gauge, gas-water separator, header. 6, the cyclone structure and working principle

When the once through boiler for hospital after a failure should be promptly dealt boiler, auxiliary equipment occurs due to the abnormal tiny leak or the boiler itself and burn local overheating phenomena, after timely treatment (timely stop or pause), can resume normal operation, depending on the boiler malfunction. After the boiler failure if not promptly treated, may lead to an accident, it must be given sufficient attention. Boiler equipment operation at any time are likely to be some anomalies, but behind these phenomena are often some kind of operating equipment failures and accidents aura. Which in addition to defects in the equipment itself, but also may be due to unskilled personnel to run the operation, negligence or misuse caused. Therefore, the operating personnel not only to master the technique, but also master the basic method to determine fault in order to properly determine and deal with failure, to avoid accidents and reduce losses in accordance with the operation of some of the anomalies. Typically, substantially determine the fault or accident three main methods, i.e., direct analysis method, the indirect method of analysis and synthesis. Direct analysis method is based on boiler operation intuitive phenomenon, with human sensory organs and experience to directly determine the point of failure, which is a basic method. With the growth and continue to accumulate experience in running time, it will use this method skillful. Indirect analysis method is based on professional knowledge-based, to determine the accident or malfunction by the process of logical reasoning under the direct control analysis, familiar with the equipment system premise. To achieve timely detection of faults and correctly determine fault, only to master the direct analysis is not enough, because most failures or accidents, often showing one or more indirect, implicit in the initial phenomenon occurs, it will not It can accurately judge. Therefore, the operating personnel in mastering the direct analysis at the same time, to gradually learn and become familiar with the indirect analysis. Occurs such as when the boiler flue gas temperature is low, the fault can not be determined directly, but indirectly by analysis of the heating surface can reflect a defect. Comprehensive analysis is a direct analysis method and indirect analysis of organically combined. For the gradual failure implicit features, with particular attention to the comprehensive judgment. This method is based on the surface of several phenomena, the main feature to check to find malfunction in the integrated cross several phenomena, determine the nature of the fault and the final position. Then, take appropriate measures to prevent the failure to expand. In short, the operation of the boiler, when the abnormal phenomenon, should find the problem in different ways according to experience, to determine the nature and location of the fault. In the current, the more Instruments, higher degree of automation, the operator can find signs of failure or an accident situation by displaying the instrument, and then checked again to confirm targeted fault location.

Using Ultraten wings condensation once through boiler for hospital technology has greatly enhanced heat the heating rate; silicon alloy material design to achieve the depth of the condensing heat exchanger, high efficiency, high heat transfer speed. "APH the T7" ready to use the factory mode, the system design is simple and clear, i.e. security that is used, the best burner performance debugging the factory, the user can simply set up at the installation site, connected to gas, water, to a flue , it covers an area of ​​greatly reduced.

Once-Through Boilers | Boilers - Product Lineup

Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants, raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment, allowing an operator to reduce its fuel consumption and CO 2 emissions.
