industrial heavy oil steam boiler for textile
Some knowledge boiler Introduction: boiler is an energy conversion device, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. Today introduced are several little knowledge about the boiler. 1, a way to improve the efficiency of the boiler A which:? ⑴ low heat losses: prevent heating surface fouling and coking, the rational use of the burner, controls the blower inlet air temperature, water temperature of attention to the impact, into the furnace to avoid excessive wind note impact milling system operation; ⑵ mechanical incomplete combustion to reduce heat loss: rationally adjust the fineness of pulverized coal, the excess air ratio control of appropriate, attention combustion adjustment; ⑶ quality assurance fired boilers; ⑷ reduce soda losses: guaranteed boiler quality water supply, installation and maintenance to improve the quality of the steam separator means, to maintain the operation of the boiler load, the water level, steam pressure and other parameters of stability, so that the boiler water separation apparatus operating under normal conditions; ⑸ index management adhere to the small boiler. ? What are the reasons boiler fire answer: ⑴ low boiler load, low temperature furnace, combustion temperature, combustion oil investment is not timely; ⑵ poor coal quality, low volatile matter, ash is too large; ⑶ air volume to adjust properly, once too high wind speed, wind powder imbalance, the excess air ratio is too large; ⑷ excessive negative pressure maintaining furnace; ⑸ bunker powder level is too low or fallen powder to the powder to make the powder unevenness; ⑸ large depression coke furnace, disturbances in the furnace is too large; ⑹ ash, coke playing time is too long, especially large caused by cold air leakage into the furnace temperature drops to a low load; ⑺ blast furnace tube, a large number of soft drinks into the furnace; ⑻ fire protection action; ⑼ device malfunction, such as sending, fan, tripping of mill, Auxiliary disappeared.
Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
Method for safe operation of industrial steam boiler for textiles steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Steam boiler furnaces operating point of the device first starts the circulation pump, the circulation pump outlet pressure, the furnace, the furnace pressure, and the system should ensure the return pressure in the normal range. Circulation pump run for 30 minutes before entering the next step, the system is stable. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, once the accident shut down the phenomenon occurs, the device automatically interlock the burner will be protected, should be promptly cut off the natural gas pipeline, furnace cleaning function should be started. Replace the rest of the gas stove, and stop cleaning. The system load requirements, temperature requirements and thermal oil outlet, the burner can automatically adjust the size of the fire source.
Temperature protection device during the fuel industrial steam boiler for textile over temperature to regulate protective effect of temperature protection is an important procedure fuel steam boiler safe operation is particularly important for the regulation and protection of the boiler temperature of the fuel vapor; at the same time to regulate in the fuel steam boiler overtemperature Protective effects. Conventional boiler temperature protection means is a bimetallic temperature controller. Flame protection: prevent explosion of the furnace, steam boiler fuel flame protection means must be provided, is a function of combustion (including ignition, combustion or misfires when halfway off, typically within five seconds reignition monitoring the furnace, a second the run off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds purge, automatically cut off and various auxiliary blowers supply the boiler operation stops. role is to monitor the flame signal the presence of a flame or an interrupt control apparatus mainly using a photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an infrared type or ultraviolet type a photoelectric conversion element, the working principle of the light converted to the corresponding strength of the radiation strength of current and the linear output state, sometimes weak induction current, through amplification, in order to have an effect on the controller.
