Ultra-low-load operation harm to oil-fired boiler for the oil-fired boiler engaged in related to people may often hear the ultra-low-load operation, what is the ultra-low-load operation? Ultra-low-load operation What are the disadvantages for the boiler? For oil-fired boilers is 60% to 100% of rated load. Ultra-low-load operation is deemed to run below this range. But while a hazardous phenomenon ultra-low-load operation of the boiler will be mainly are: (1) the reliability of the boiler water circulation drop of fuel gas circulation usually natural circulation. Ultra-low-load operation, because a small amount of fuel into the boiler, the temperature drop across the furnace, the heated water wall weakening, boiler water circulation flow rate will be reduced, reliability is lowered circulation. (2) it is difficult to ensure the quality of the paper making automatic steam boiler load decreases as the fuel, the temperature and humidity of the steam will be affected, in particular for a boiler with a superheater, when the boiler load decreases, the outlet steam temperature corresponding decline difficult to maintain rated steam temperature, steam quality deterioration. When the superheated steam temperature drops below nominal, soda heating surface system conditions will enter the danger zone, when the load is technically called the minimum allowable load. (Three) tail heating surface of the boiler, air preheater, such as acid etching, and a tail economizer heating surface of the hot water boiler generally increased in line with the normal boiler heating surface design and exhaust gas temperature, exhaust gas temperature is usually high dew point temperature. Ultra-low-load operation, the furnace temperature was decreased to varying degrees departments, the final exhaust gas temperature will be reduced. Low Temperature easy to make a metal wall temperature below the dew point of sulfuric acid vapor, sulfuric acid vapor condensation heating surface will be at a low temperature, resulting in low corrosion of heating surfaces. Thus, in the operation and management of the boiler, the boiler should try to avoid the occurrence of ultra-low-load operation. Ultra-low-load operation harm to oil-fired boiler is too big, so we have to load the main boiler of time not less than the rated load in their daily operations.

As a global boiler enterprise, Fangkuai Boiler attaches great importance to the opportunity of communication with customers. Therefore, we have set up a sales team of more than 100 people to visit customer units regularly to check the boiler operation status. Not only can timely search the customer's use feedback and boiler improvement opinions, provide a clearer development direction for equipment research and development, but also assist users in the testing and commissioning of boilers and maintenance work, full life cycle services, and solve customer cooperation projects. The problem is that nobody cares ".

When atmospheric pressure using the direct pressure hot water boiler heating system and water or closed loop. That is, on the boiler body with the atmosphere of the exhaust pipe as a return pipe use, the boiler water pressure is always in full state. This closed loop harm in two ways: The first is when the water temperature is too high furnace, steam generated can not be excreted, so the pressure will continue to rise, explosions and spills can happen at any time. Second, even if the boiler water temperature is not high, it does not produce a large amount of steam, but the role of a circulation pump, the boiler body is subjected to high pressure hot water circulation. The pressure hot water boiler installed in the basement or on the first floor, the hot water storage tank installed on the roof, this embodiment is similar to the boiler to the atmosphere as exhaust pipe return pipe use. Although the boiler is not subjected to the pump pressure applied to the ring, but at all times are under boiler water holding tank to provide a high static pressure, the higher the floor, the higher the static pressure of the hot water.

Buy electric boilers do not follow suit, refer to the following five points to be sure: electric boiler using electricity as a fuel source, no pollution, intelligent operation is very simple, increasingly popular in the market, many families have joined the purchasing the ranks of the electric boiler, in fact, not all business units are suitable for electric boilers, blind purchase will fall into errors in the purchase. 1, the electric boiler incomplete knowledge, blindly follow the trend. Sometimes it might require less heating heating equipment, rather than electric boilers. 2, do not ask for more views of users used the electric boiler, to the mall or factory direct purchase. There are many users in a simple to understand after the boiler directly buy electricity, no more asking people who used electric boiler, this case is the use of electric boiler can not be a case of direct purchase. 3, the electric boiler brands do not understand, do not know what brand of electric boiler is better. This calls boiler is a new product on the market and there is no fixed pattern, there is no example of a good brand, so there are many brands of electric boilers are mixed, and more consumers can compare and choose the most affordable products. 4, some of the electrical parameters of the boiler and power consumption do not understand, many users do not currently know some of the basic parameters for the calculation of power consumption and electric boiler.
