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).

How natural gas steam boiler steam boiler model selection natural gas main type WNS and SZS type Both models can burn natural gas, liquefied petroleum gas, coal gas, coke oven gas, biogas, including steam boilers and small oil boiler hot water boilers, gas concrete how the selection of steam boilers, we take a look. Due to the different sectors of production processes, demand for steam boilers are also different, and therefore, when the gas steam boiler selection, need to have enough knowledge of the production process, in order to make the right selection and design of the boiler. 1, selection of technical parameters: gas comprising steam boiler rated evaporation, rated steam pressure, steam temperature rated, e.g., general pressure chemical production requirements are not too high, the pressure required to produce 10 kg as an example, then the boiler design pressure of 1.25 MPa is necessary to use; 2, ancillary equipment options: supporting auxiliary gas steam boiler main control cabinet, water supply pump, circulation pumps, burners, sub-cylinder, water treatment equipment, energy, a condenser, users can choose according to their own needs and price configuration; with the Earth's atmosphere deteriorating, I believe that we Chinese citizen environmental awareness is still very strong, in order to reduce pollution of the planet, we must first consider how environmentally friendly energy-saving performance, then consider fuel, gas boiler combustible gases, polluting emissions, environmentally friendly energy-saving ideas. Boiler pressures, consider the problems caused by an explosion caused by overpressure, and even carbon dioxide poisoning incidents. In the control of gas-fired boiler operation, select the better it is simple and easy to operate.

Gas boiler shutdown normal shutdown process step is one step in the process of boiler operation is essential to understand the shutdown processing methods to ensure more long-term operating life of boiler. When the boiler the following faults can temporarily shutdown for maintenance. Expansion port, leakage rivet joints; tube, the waterwall tubes, damage to the heating surface tube leakage; drum in contact with the flue gas, set top box, a heat insulating material off the downcomer; water supply system, a combustion system, the occurrence of breakage safety accessories . Shutdown of the gas boiler normal (full shutdown, maintenance shutdown) Step 1, in order to stop the burner, for closing the valve. At the same time feed water to the boiler, 2cm above the normal water level reaches the stop water supply, reduce the pressure. 2, close the main steam valve, open the traps, steam boiler, water cut off. 3, the electric boiler feed water control valve closed and the manual valve, boiler feed water cut. 4, steam pressure may be lowered to the water supply and drainage operations alternately 0, the pot water temperature is gradually lowered. When the temperature dropped to 50 ℃ (not hot when hand potshell head with or touch), the entire pot of water may be drained. Should be preceded by opening the drain valve or air valve above the boiler, this time into the furnace maintenance, shutdown must be kept slow cooling, rapid cooling is prohibited. From the shutdown to be able to enter the furnace maintenance, cooling time is not less than 24 hours. 5, sales of more than 24 shutdown, to total gas supply valve is closed, opens the gas pipe to completely drain the subjective dispensing gas.

25 tph SZS condensing gas-fired steam boiler project for food industryA steam boiler is a piece of vital equipment in the production processes of food industry such as stewing, drying, concentrating and sterilizing.  Jiaozuo Yuzhu Instant Noodle Company, affiliated with Henan Province state-run Boai Farm, is a national professional manufacturer of instant noodles with the annual production capacity of over one hundred thousand tons; the instant noodles produced by the company are sold very well all over the country. China is advocating the development of green economy in recent years; Henan Province is vigorously controlling pollution and reforming coal-fired boilers to gas-fired boilers. As the only state-owned enterprise of instant noodle industry, Jiaozuo Yuzhu Instant Noodle Company actively promoted the "coal to gas" action and ordered one set of 25 tph gas fired boiler (SZS25-1.25-Q) from ZOZEN. The boiler is equipped with a large volume furnace and an advanced imported low NOx burner to effectively reduce the NOx emission. In addition, the boiler adopts the design of membrane water wall; the gastight test must be done before installing thermal insulation layers, to ensure there is no flue gas leak under the condition of micro-positive pressure combustion and help reduce the heat loss of the boiler body; the thermal efficiency will reach up to 98%.
