steam boiler for heating

20 tph SZS gas-fired steam boiler for heating for cigarette factoryChina Tobacco Shiweice(Yunnan) Reconstituted Tobacco Co., Ltd. mainly targets the Chinese cigarette market. Due to the need of production development, China Tobacco Shiweice adopts the most advanced papermaking method to reconstitute the tobacco leaf production process. Remanufactured tobacco needs a large amount of steam in production. The previous boiler's supply can not meet the demand for new production processes. After the natural gas direct supply pipeline project was completed, China Tobacco Shiweize ordered a 20 tph gas-fired steam boiler with natural gas as fuel from ZOZEN boiler through a bidding activity. The body and hearth of the series boilers are surrounded by membrane-type water-cooled walls, and use micro-positive pressure combustion, there is no cross-talk problem, the operating environment is without pollution.

Gas-fired boiler is one of the most widely used equipments in industrial production, and many problems of water use are solved by it. In order to ensure that gas-fired boiler can maintain a stable working state for a long time, it is essential to maintain the boiler correctly. If the gas-fired boiler has been shut down for a long time in the past, how can it be restored to normal? The first is to thoroughly clean the gas-fired boiler. Since it has not been used for a long time, then the gas-fired boiler is bound to accumulate a lot of dust from inside to outside, and only after it has been cleaned up can it be used. In order to clearly check out the actual situation of the boiler. After cleaning the gas-fired boiler, be sure to use the Hot air desiccates it, but it cannot be heated at the same time for walls and other fittings, which may have adverse consequences. The correct way is to place an electric heater at the bottom of the gas-fired boiler and heat it. When the gas-fired boiler is put into use, it is also necessary to place desiccant on the corrosion-proof tray, so that the tray can keep a good drying effect, which is helpful to its normal use, so as to promote the efficiency of the gas-fired boiler to be brought into full play. In addition to the long suspension of gas-fired boilers need to pay attention to the above operation, daily maintenance is also very important, must pay attention to the inspection of desiccant every few months, timely Add and inspect boiler fittings regularly, repair or replace them in time if they are damaged. On this basis, the gas-fired boiler can be restored to the previous good performance, to provide the heat source needed for industrial production, so that its value can be brought into full play. What do you need to pay attention to when gas-fired boilers feed water? According to the requirement of water quality of gas-fired boiler, if the water quality of boiler is too high, it should be treated by supporting water, which can soften the hardness of water and reduce the fouling in boiler tube, so as to improve the service life of boiler and reduce the operating cost. Water should be slowly added to the steam boiler for heating when water, feed water temperature should not be too high. Water can not be added too much, as the temperature increases, water will continue to expand, resulting in waste. Generally add water to the normal water level gauge, that is, the middle line can be, now the boiler is equipped with intelligent water equipment, as long as the intelligent adding water can be turned on. When adding water to the boiler, remove the air from the economizer and boiler pipe.

What is the condensate recovery? Why steam condensate recovery steam system is an important measure energy? In industrial production, steam as an extremely versatile energy and almost all businesses are inextricably linked. A large number of industrial water and coal-based energy is used to generate steam, and steam is used to heat industrial production process, the steam generated in the heat releasing section condensed water is often thrown away. Condensate has a large amount of heat, usually accounts for about 20 to 30% of total calories steam, some devices may be up to 40%. Thus if the temperature condensate as boiler feed water recycling or secondary flash steam utilization, not only to save the water for industrial use, but will save a lot of fuel. Thus, in the production of the same multi-boiler steam, it can save 30% to 40% of fuel, water and water treatment chemicals. At the same time reduce fuel economy of boiler flue gas emissions, protect the environment. Condensate Recovery Value Embodiment: A thermal energy recovered in condensate water, the secondary flash steam heated steam produced can be replaced with a new material; B water saving, cost saving water; C high temperature condensate as boiler feed water, the boiler heating saving makeup water consuming fuel; D vapor condensate as boiler feed water, a lower TDS content, reducing the number of boiler blowdown, heat loss is reduced sewage entrained; E reduces smoke emission and waste water contamination of soil and groundwater . However, industrial steam condensate recovered faces many technical challenges, such as the recovery pump cavitation at high temperature condensate; closed directly boiler feed water; recovering the vapor-liquid two phase flow; contaminated condensed water recovery; high-temperature condensate and boiler feed water at room temperature the temperature of the water supply caused / pressure and poor. HUAWIN (China News) company as the world's leading experts in the steam treatment, using its own patented technology, customers can not only provide complete condensate treatment programs and products, and provides turnkey services and EMC, as do their Chinese energy conservation contribution. Condensate Recovery mode 1. Open the recovery, recycling closed 2. Direct recycling, indirect recycling 3. Restore recovery, heat recovery, flash recovery 1, closed recycling unit: There really grasp the closed recycling technology manufacturers very little , a true closed-recovery units, should address the following questions: 1) to ensure no leakage at the same time, when the incident level is too high to solve the overflow drain problem, that is, when the drain, the same can not leak. 2) stop after an accident, pour water through the cooling tank, the tank may have a negative pressure when the device is restarted, it may cause the pump suction side pressure is too low, it is necessary to solve automatically eliminate the negative pressure in the tank The problem. 3) high-temperature condensate water pump cavitation may cause problems at runtime. 4) When the condensate pump is turned on, the vortex is easily formed, the flash vapor suction pump inlet. 5) the secondary flash steam condensation problems inside the water tank drawn out. Only real solution to the above problems, in order to be truly mastered the core technology of closed recovery. 2, steam-driven pump: HUAWIN (China News) Steam Pump Company truly master the core technology, in addition to the key components are imported, the parts using CNC machining centers precision machining, precision brand has more than similar imported products. And it has developed a large flow pump, a single pump can deliver water to reach 35t / h.

Dairy production and processing sectors, need a lot of steam on food drying, sterilization, stereotypes, such as processing, steam boiler for heating essential.
