A small category 1 gas heating cast iron boilers, soft drinks dual small boilers: Rated evaporation does not exceed 0.5 t / h, rated steam pressure not more than 0.04 MPa; 2, a small hot water boiler: rated does not exceed 0.1 MPa water pressure, water pressurized hot water boiler; 3, small steam boiler: water no more than 50 liters capacity, rated steam pressure does not exceed 0.7MPa; 4, small pressure boiler aluminum: aluminum bulk material selection, not the rated steam pressure outlet than 0.04 MPa and not more than 0.2 rated evaporation t / h.
Such as hotel Home Hotel Group is one of the three major brands, in 300 cities in the country has nearly 2,000 hotels. Home Inns has won China Golden Pillow Award for Best Chinese economy hotel chain brand award, in 2014, Home Inns brand value of $ 420 million of selected China's top 100 brands. April 4, 2016, BTG hotel groups such as the privatization of the hotel purchase transaction has been completed delivery. In mid-2016, as a Beijing hotel with our preliminary communication, the urgent need two heating cast iron boilerss work of heating and hot water supply. I related technical engineers and recommend it to calculate the number and size of the boiler on the hotel room as hotel Willy sharp V6-99 two models.
Shutdown of the protective measures during the necessity and reasons boil heating cast iron boilers boilers, which during the shutdown, if you want to take some protective measures? Why boiler boil? In addition, the boiler thermostat should be how to set the start and stop temperature? All these questions and boiler-related products this important site, so the following, to explain in detail and answer, so, so that we have a correct understanding. 1. During the boiler shutdown, if you want to take some protective measures? Boiler, during which shutdown is to take some protective measures, because if you do not, then, the internal boiler corrosion of the metal surface will produce dissolved oxygen and temperature in an oxygen effect, especially in the superheater section . So, to take some precautions to avoid this problem inside the boiler, is the rusty metal corrosion. 2. boiler thermostat start and stop temperatures, how to set? Boiler thermostat, which is an important component, so its start and stop temperature setting, is an important work, and can not be careless treatment, so the following to briefly explain. Start temperature setting thermostat: the thermostat on the power cord plugged into an electrical outlet, the digital display face panel, press the start set the "+" key or the "-" key to start temperature set up. At this time, the temperature of first table shows the thermostat, the temperature is to start the circulation pump. Thermostat temperature setting stop: it is very simple, just stop setting the "+" key or the "-" key to stop the circulating pump set temperature, the temperature of the first table shows the , it is to stop the circulation pump temperature. 3. Why boiler will boil? Boil boiler, mainly by two reasons caused. First, if the boiler and radiator heat boil, then excessive heat boiler, then, should be pressure treated fire. Second, if the boiler boil, but the radiator normal, then the tube is connected to the boiler in question, then, should be to find and repair, to solve the problem.
Condensate recovery heating cast iron boilers 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.Free Chat
