For different working pressures rice husk fired boiler exported to thailands, to have a separate steam pipes and water pipes, respectively. If when a combination of the main steam pipe, the steam pipe to be fitted with high pressure apparatus and the automatic depressurization safety device that prevents the low-pressure side of the overpressure. When the water pressure does not exceed 20% of the maximum pressure, the system can feed water to the boiler feed water from the total.
1.4MW YQW series gas-fired thermal oil heater for medical material industry
In the R&D and production process of medical materials, sterilization and disinfection processes have put forward high requirements on temperature. The boiler can be said to be the indispensable important equipment in the medical industry. Nantong Kedi Medical Material Co., Ltd. is a professional company specializing in the research and development of medical materials such as dressings, designer materials, disposable medical consumables and surgical hygiene products.
A rice husk fired boiler exported to thailand operation must be controlled and stable operation of secondary causes of boiler steam temperature control stability of a secondary steam temperature has important implications for safe and economic operation of the unit. When the steam temperature is too high, it can cause overheating, a portion of the metal to reduce the strength of the reheater, and the steam turbine pipe cylinder and a rotor, resulting in shortened life of the equipment. Severe over-temperature, it will also enable the heating surface blasting. When the steam temperature is too low, the effect thermodynamic cycle efficiency, and a steam turbine final stage blades at excessive humidity, severe water hammer may occur, resulting in damage to the blade fracture accidents. When the steam temperature substantially sudden rise dump, large thermal stress is generated in addition to the heating surface of each weld and the outer part of the boiler is connected, will cause the relative displacement between the cylinder and the rotor of the turbine increases, i.e., the expansion difference increases, severe or even static friction wheel and the separator, causing severe vibration. In addition both sides of the turbine steam temperature deviation is too large, both sides will uneven heating turbine, uneven thermal expansion. Therefore, the operation of the boiler steam temperature to closely monitor, analyze, adjust, control steam temperature stability with the most reasonable method.
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 rice husk fired boiler exported to thailand welds is more guaranteed.
