One condensing gas boiler is about 70-75 cubic meters of gas consumption, gas consumption in the gas boiler general less than 80 cubic meters. Of course, different boiler manufacturers produce equipment boiler gas consumption will be different.
Hefei Limin Pharmaceutical Co., Ltd. Nanjing Military Region, formerly the backbone of pharmaceutical companies, the main drug is slowly swallow rather teabag, relying on advanced R & D platform to carry out contract manufacturing, OEM OEM and other business cooperation. China's environmental protection development trend began to take shape, many environmental policies have been put forward for a positive response to the national environmental policy, Limin Pharmaceutical decided to introduce a gas station 3 ton straw pellet fired steam boilers. After an investigation of the boiler market, Limin Pharmaceutical fast boiler is strong comprehensive strength and wealth of experience working for many years in the pharmaceutical industry to attract, party fast according to the actual needs of customers for its recommendation of one of Taiwan 4 tons of steam condensate gas-fired steam boiler (WNS4-1.25-YQ).
Condensate recovery boiler of Embodiment 1, how the recovery boiler steam condensate recovery system recovering exhaust system high-temperature condensed water, the condensed water can maximize the use of heat, water conservation, fuel economy. Condensate recovery system can be divided into open and closed recovery system recovery system. Recovery system is open to a condensate recovery tank to the boiler, the condensed water recovery and utilization in the process, one end of the recovery pipe is open to the atmosphere, i.e., the condensed water collection tank is open to the atmosphere. When the lower pressure of the condensed water, can not be reached by the pressure from recycling properties, high temperature condensed water pump pressure-feeding. The advantage of this system is that the device is simple, easy to operate, a small initial investment; however, a large area of the system, resulting in low economic efficiency, larger environmental pollution, and since the condensed water is directly in contact with the atmosphere, dissolved oxygen concentration in the condensed water improved, easy to produce equipment corrosion. This system is suitable for small vapor supply systems, a small amount of condensate, small amounts of secondary steam system. When using this system should minimize emissions of secondary steam. Condensate recovery system is a closed tank and all piping are set at constant pressure, the system is closed. Condensate system has most of the energy recovery through a certain recovery device directly to the boiler, the condensed water recovery temperature loss in the cooling portion of the pipe network only, since closed, quality assurance, the water reduces the cost of recovery into the boiler . The advantage is economic good condensate recovery, long working life of the equipment, but the system is relatively large initial investment, operation inconvenient. 2. Select recovery methods for different condensate reconstruction project, which way the recovery and recycling equipment selection, is whether the project can achieve the purpose of investment crucial step. First, we must accurately grasp the condensed water condensate recovery system, if the condensed water is not calculated correctly, will make the condensate pipe diameter selected too large or too small. Second, to properly control the pressure and temperature of the condensed water, which embodiment uses the recovery system, which device, how to arrange the pipe network, the condensate temperature and pressure are related. Third, the trap condensate recovery system is selected to be noted that the content, wrong trap selection, will affect the pressure and temperature at which condensation water use, also affect the normal operation of the recovery system. Recovery efficiency is not as high as possible in the system selection, but also consider economic issues, that is considered waste heat utilization efficiency, we must also consider the initial investment. Due to the high efficiency of closed recovery system, less environmental pollution, are often preferred.
But because of water quality problems, so can easily result in a fine diameter pipe scaling, or even blocked. And because of its parallel manner (e.g., by way of serial interfaces, interfaces intermediate too, the inner surface is not smooth, easier scale, and need to consider the expansion, leakage and other issues), wherein a particularly likely to cause the occurrence of scaling phenomenon unit then the cells are more prone to fouling the scaling, fouling the more easy to scale, all impurities are in many cycles in this cell block. And because the other three units in the unit after blocked, water can still walk normally, all fouling of the cell it is not easy to be found, the boiler will not prompt alarm. Until the unit due to the long dry leaking, causing the failure, the user will know, but it was too late to repair, must be completely replaced.
