three pass wet back fire tube boiler

Boiler water softening equipment features and characteristics of the important role of three pass wet back fire tube boiler water softening equipment in the food industry and the important role of boiler water softening equipment primary effect is to protect food companies boiler equipment from corrosion in the food industry in this way, can effectively prevent the accumulation of the pipeline many of scale affect the efficiency of infection, decreased heating effect, the device selection of the world's most advanced skills, has a small footprint, high efficiency, long life and other characteristics of use, is the water treatment industry sought-after products. Food industry features a high degree of automation of industrial boiler water softening equipment. Fully automatic boiler water softening device according to the preset program, complete the cycle of softening active regeneration, in addition to the need for periodic manual operation outside the regeneration salt to increase without any manual operation, to save a lot of manpower, material. We supply active control or active control computer (optional) allows the user to adjust the operation of the whole system is based on changes in water quality. Water quality stable. Water softening equipment according to local water quality, accurate setup, in any case can ensure water quality. High efficiency, low energy consumption, low running costs, because the device all reasonable planning and the implementation of strict control of the initiative, the exchanges to ensure the full competence of the resin, the salt consumption, water consumption and other target devices are significantly lower than the general softening water equipment. Reliable operation, the use of long life. AC selection device housing softener manufactured from high strength composite materials particularly glass and steel, corrosion, aging, up to 50 years of useful life, fully automatic control of the unique valve structure planning, the valve body is the only moving parts, so that these features reliable valve control functions, the use of long life. Small footprint. Advanced process planning the water softener equipment, compact structure, significantly reduced footprint, saving construction investment. Very wide use.

Response to national environmental policy in recent years, Changzhi City, various enterprises and institutions from themselves, have the three pass wet back fire tube boiler environmental transformation and selection. However, due to various boiler plant manufacturers of products of varying quality, there is a variety of security risks in the operation; taking into account the level of professional fireman some units of non-compliance, the boiler operating procedures less skilled, the above reasons, Changzhi City Special inspection at this year's "safety month" held gas boiler safety planning activities of technical training courses, the city's use of gas-fired boiler units represent 233 enterprises and safety training. Fast boiler has a strong position in the field of clean-type gas boilers, and has a wealth of experience. Changzhi City, the special prosecutor of the special fast Boiler training for each unit represents.

In Jan 2009, a power plant order in Vietnam ordered a set of 75 ton Coal fired steam three pass wet back fire tube boiler from our ZG company. ZG manufactured 75 ton DHL coal fired steam boiler can supply stably steam to power plant. And this power plant uses steam to generate electrics power finally. ZG manufactured 75 ton coal fired steam boilers have advantages of high quality, good performance, less pollution, etc. Our consumers from Vietnam visited our coal fired steam boilers manufacturing sites. And then our engineers directly negotiated with them about their needs and requirements. After several communications, both parts signed a sales contract about purchasing a set of 75 ton Coal Steam fired boiler to power plant finally.

Common steam three pass wet back fire tube boiler overpressure accident approach: 1, the phenomenon (1) steam boiler overpressure sharp increase in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line" safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the boiler furnace internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Steam boiler accident and the type of treatment and the boiler safe to use common sense
