Recommended heating methods for B&B hotels—Huanrui intelligent electric floor heating
Going out for vacation has become a way of people's leisure, and commercial hotels and homestays have become places where people go out to live. Compared with cookie-cutter, standardized decoration, and commercialized hotels, homestays pay more attention to taste and have more diverse designs. They are not only beautiful and comfortable, but also have their own stories, which are loved by many young people. But B&Bs are generally selected on the edge of mountains, rivers, lakes and seas, with beautiful scenery and fresh air. But in winter, the temperature of remote homestays is lower and the weather is cold, and people's desire to travel will be relatively reduced. These homestays often encounter the curse of "coldness" in winter. Imagine that when tourists stay in a B&B hotel in winter, they can meditate on the floor with bare feet, soak in the hot springs and watch the stars. Do you need to worry about the occupancy rate? Which heating method is more suitable for this homestay? Many homestays and hotels first think of installing central air conditioners in terms of heating methods. Although it is easy to control, convenient and flexible, the heating of air conditioners is air convection heat dissipation, and the comfort is relatively poor. Feet never get warm. In addition, the auxiliary heating function may be required for air-conditioning heating in mountainous areas where the temperature is too low, thereby increasing the operating cost of the hotel. In addition, since homestays are generally built in areas near mountains and rivers, infrastructure such as pipeline gas may not be perfect, and wall-hung boilers using gas heating are also limited. Therefore, the more recommended homestay heating solution is the Huanrui intelligent electric floor heating solution with electric heating. (Note: The above pictures are from the Internet, if there is any infringement, please contact to delete) Choose Huanrui Easy to install The heating cable is buried in the ground, and the floor or tiles are laid on it, and there is no other complicated heating equipment. Energy saving Electric floor heating uses clean energy and electricity, and the conversion rate of electricity to heat is as high as 98%. It can be heated immediately when it is turned on. It can save energy by about 40% compared with other heating equipment. Intelligent temperature control The electric floor heating intelligently divides the room temperature by time, and the unused rooms can be closed, saving energy without wasting electricity. Heating is as flexible as an air conditioner, but the comfort level is higher than N levels. Comfortable and healthy Electric floor heating radiates heat from the ground, the heat is distributed evenly, and the heat is transferred from bottom to top, which is in line with the health care principle of "warm feet and cool top" in traditional Chinese medicine; it does not cause convection of dirty air, keeping the room clean; the heating process is sil...

  • Application of heat tracing and insulation of Anhui Huanrui electric heating system for white oil storage tanks in Karamay Oilfield of PetroChina
    PetroChina Karamay Petrochemical Company is located in Jinlong Town, Karamay City, Karamay District, Uygur Autonomous Region. The white oil hydrogenation unit is currently one of the few domestic devices that use more advanced hydrogenation methods to produce white oil products. It produces a variety of specifications. White oil is widely used in industry, cosmetics, food, medicine and other fields. The white oil products of various brands and grades produced by Karamay Petrochemical Company have been popular in the domestic market, with high reputation and popularity and considerable economic benefits. In response to the various needs of the heat tracing project of this device, Anhui Huanrui provided a complete set of electric heat tracing solutions. Project difficulties 1.The reaction temperature changes greatly, and the catalyst activity is easily affected. The white oil high-pressure hydrogenation unit is a high-temperature, high-pressure hydrogenation catalytic process. After the raw materials, catalysts, and pressure are determined, temperature is the main factor affecting desulfurization, denitrification and conversion rate, and it is also the main means to control the reaction depth. For the first-stage reaction, appropriately increasing the reaction temperature can increase the desulfurization and ammonia removal rate, reduce the pollution and poisoning of the second-stage catalyst, and create conditions for the second-stage reaction. However, the reaction temperature is too high, especially when the bed temperature is too high, on the one hand, the cracking reaction of the reactants is increased, so that the low boiling point components increase, and the yield decreases; on the other hand, the bed layer is caused to accumulate coke and the pressure drop increases. The catalyst life is reduced. Therefore, during the production process, the reaction temperature needs to be kept within an appropriate range, and stable and continuous. 2. The pipeline has steam purging requirements, the highest temperature can reach 200 ℃ Steam purging is suitable for conveying power steam pipelines or thermal pipelines, purging with large flow of steam, and the flow rate is not less than 30m/s. Press steam-slowly raise the warm tube-constant temperature for 1h-purge-stop the air to cool down-reheat the pipe to increase the temperature, constant temperature, the second purge, and this repetition is generally no less than 3 times. Under long-term high temperature conditions, the electric heating cable needs to ensure normal and stable operation under high temperature conditions, and must withstand a temperature of 200°C. Solution In order to further confirm whether the electric heating cable can meet the reaction temperature. Before the installation, the company's engineering department cooperated with the main business unit to conduct field tests on the heat tracing performance. The heat tracing has a fast heating speed, high temperature resistance, temperat...
