4 tons of steam boiler before firing what needs to be done to prepare a deal boiler conduct a comprehensive inspection before Sheung Shui, the water is softened before boiler water filling. 2, Sheung Shui should check whether there is water leakage valve, leaks should be immediately removed when found. 3, the check Sheung water temperature, pressure gauges, water level, no good production of inlet and outlet valves, smoke profile, said shutter is flexible, the flue gas channel is smooth duct, each cleaning doors are tight. 4, before firing coal with water 8-10%.

Steam boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).

The boiler is the most important part of a central heating system. It's like a big fire that has a continuous supply of natural gas streaming into it from a pipe that goes out to a gas main in the street. When you want more heat using for central heating, you switch on the boiler with an electric switch. A valve opens, gas enters a sealed combustion chamber in the boiler through lots of small jets, and an electric ignition system sets them alight. The gas jets play onto a heat exchanger connected to a pipe carrying cold water. The heat exchanger takes the heat energy from the gas jets and heats the water to something like 60°C (140°F).

The working principle of steam boilers and steam boilers for industrial structural features has brought great convenience, steam boilers led to the development of the times, the following small series to introduce you to the structural characteristics and working principle of steam boilers. Steam boiler is producing steam-based machines, people use a lot, but many of its structure and working principle are not fully aware of, it is the use of volume and pressure water tube steam boilers coal, oil and natural gas are less restrictive , I would like to have a lot of space, but also easy to arrange, in the form of a variety of steam boilers. Water in the steam drum is heated into steam, the heat emitted by the fire in the furnace, is the principle of steam steam boiler. Steam boiler works: 1, heat generated by burning coal in the furnace, the heat transfer by radiation is first absorbed waterwall waterwall Boiling water, a large amount of steam into the drum for water separation (except the DC furnace), separated saturated steam enters the superheater, and continues to absorb the furnace top horizontal flue by means of radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Generating steam boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. 2, when the pulverized coal fired boiler work, the center position of the flame will impact the amount of evaporation, generally, the lower the evaporation flame kernel, the flame kernel high evaporation amount is small, the center position of the flame will also affect the reheat steam or superheated steam temperature, generally lower the center of the flame in particular superheated steam is then superheated steam temperature to be low, otherwise higher. 3, the arrangement of the burner, pulverized coal fired boiler on, the current embodiment there are opposed wall, more Tangentially combustion, combustion bis Tangentially the like, each have their own characteristics, can not be applied because the same furnace at the same time several above-mentioned arrangement, the steam still can not directly affect the conclusion. Steam boiler structural characteristics: 1, the steam boiler body welding: the main welding using advanced submerged arc welding process, welding quality assurance. All welds were 100% primary radiation detection according to the "Steam Steam Boiler Safety Technology Supervision", according to the eligibility criteria Ⅱ pole. 2, a horizontal steam boiler combustion three return all wet back structure. 3, before steam boiler, after the smoke box sealed with high temperature are graphite asbestos material, a reliable seal, to ensure that the steam boiler flue gas does not leak when run under a slight positive pressure conditions. 4, pipe thread: the second backhaul convection heating surface of the steam boiler, we used a threaded pipe, enabling the efficient heat transfer. Enhanced heat transfer, thermal efficiency of the steam boiler, a threaded tubular light pipe is equal to 2.4. Fluid flow within the tube wall near the fluid flow velocity is very low, the presence of fluid at the wall boundary layer is called, when the thermal resistance in series of several heat transfer water into the flue gas in the outer tube, the boundary layer the maximum thermal resistance, but the boundary layer is thin, as long as the boundary layer of little disturbance, as in an ordinary pressure in a pipe wall to the boss, the disturbance of the boundary layer, will greatly reduce the thermal resistance, is effective threaded pipe one way. 5, to make the system more energy efficient, continuous adjustment using the water supply, to avoid frequent pump start. During the period, the three-pass water smoke tube leaving a wide space, the pot to ensure natural circulation of water flow. 6, the body safety devices: at the rear of the steering steam boiler chamber is provided built-proof door, the steam boiler ignition and running, if the furnace gas deflagration occurs: timely relief, preventing the furnace deflagration, safe and reliable; as built after take-off will not hurt.
