widely used oil industrial vertical steam boiler
Oriental Hawaii Holiday Hotel is located in Xiaogan City of Hubei Province in accordance with international five-star hotel standard design, set business rooms, SPA bath, foot care, indoor spa and other facilities in one of the hotel. Hot water boiler is one of the important facilities normal operation can not be separated. With the pace of Hubei Province in response to the national defense of the blue sky, the use of clean fuels gradually increase the proportion of Oriental Hawaii hotel provides visitors to the more perfect leisure experience a sense of the original wishing more polluted coal-fired boilers to replace clean and green gas-fired boiler. After comparing several vendors boiler industry, a number of R & D results very fast square value in the field of clean fuels, entered into a collaboration with the fast boiler. Fast boiler integrally provided a 1.4MW condensing pressure hot water boiler (CWNSL1.4-95 / 70-Y.Q) according to their actual needs. Put into use, fully meet the needs of Oriental Hawaii Holiday Hotel heating and hot water supply.
Oil-fired boiler work and preparation before purchase if necessary fuel boiler induced draft fan, this is a particular kind of boiler, and all of us concerned, but also need to have a comprehensive knowledge and understanding, so as to know how to correct and rational use of oil-fired boilers this a boiler at the same time to achieve the purpose, can also increase their expertise in this area. Whether to do some preparatory work before 1 oil-fired boilers to buy? Oil-fired boiler product before making the purchase, it is the need to do some preparation work. Moreover, this work has two purposes, first, the importance of this work reflects the product purchase, and second, to avoid the wrong choice appears. In the specific content of the work, first have a clear understanding of the environment and the requirements of the product, the second is some basic information to understand the product and production manufacturers, including product origin, specifications, size, performance and technical parameters, product quality and price and product service, in the process of considering these factors are indispensable to ensure accurate judgments and the correct choice. 2. Fuel different classification criteria boiler Are there different kinds? Oil-fired boiler, which is a specific kind of boiler, so, as with a normal boiler, at different classification criteria corresponding to different species, therefore, the answer to this question is yes. If the kind of fuel according to points, can be divided into two oil-fired boilers and boiler heavy gas oil boilers, diesel or gas oil refers to the kerosene, heavy oil is extracted by means gasoline or diesel oil as the rest of the heavy oil. In addition, the boiler according to purpose to points, can be divided into a fuel oil-fired boiler water boilers, hot water boiler fuel, heating fuel boilers, boiler and fuel oil bath and widely used industrial vertical steam boiler these. 3. The oil-fired boiler fuel consumption calculations it important? From a professional point of view, to calculate oil-fired boiler fuel consumption is very important work, and careless treatment can not be ignored, because if get the wrong result, it will affect the normal use of the boiler. In addition, we also need to know is that there is a corresponding formula, under normal circumstances the use of boilers, boiler output if different, then the boiler fuel consumption is not the same. 4. Does fuel boilers must have induced draft fan? There are requirements for the quality of its oil do? Whether fuel boilers must have induced draft fan, according to this aspect of professional presentation, the answer is not necessarily, because depends on whether the specific circumstances so require, if the amount of air supply and flue fuel ratio appropriate and clear then use the blower can be. This kind of boiler oil-fired boiler, its oil quality is not clearly defined requirements, but in the use, certainly requires better quality fuel, so as to ensure the boiler work properly.
Coal-fired widely used industrial vertical steam boiler oil requirements and whether the induced draft fan: fuel steam boiler in the boiler, we believe this a boiler will not feel strange, because the front, some of its articles related to getting to know and understand it, and not know about it yet. So the following, in order to promote familiarity with all of the following, will continue to explain knowledge in this area, in order to have the learning effect. 1.20 tons of coal-fired steam boiler, the standard amount of coal every day, about how much is? 20 tons of coal-fired steam boiler, which is the standard amount of coal every day, and if, the calculation explanation, then, is the need to know the specific values, so in order to give a specific value, such as: rated steam pressure of the boiler, is is 1MPa, the water temperature is 20 ℃, the thermal efficiency of the boiler is 90%, in addition, the standard coal heating value is 7000 kcal / kg, then 24 hours a day if the full load operation, then, with its daily the amount of coal is about 50-56 tons. However, in practice, due to some unavoidable factors, it will lead to its value, and larger than 56.
Tail secondary combustion flue how to deal with the phenomenon of a sharp increase in rear of the boiler flue secondary combustion flue temperature location and later. 2, the furnace, the flue abrupt change in negative pressure, flue gas is not tight at the smoke, the Mars. 3, air preheater large current swing bearing housing temperature, severe Jam occurs. 4, air preheater fire alarm issue. 5, steam temperature, economizer outlet water temperature, the air temperature rises abnormally. 6, induced draft fan vanes automatically open a large, Fan current rise. 7, as the combustion side, both sides of the smoke temperature difference increases. Reason 1, through the coarse fine grinding coal, coal poor uniformity, improper adjustment of combustion, combustion of fuel is insufficient, serious mechanical incomplete combustion, and high levels of combustible ash accumulated in the back pass. 2, an oil burner or an oil poor atomization, so that unburned droplets deposited in the flue. 3, prolonged low load operation of boiler, the furnace temperature is too low or too small amount of excess air resulting in incomplete combustion of coal or oil accumulated in the tail. 4, after the shutdown of the fuel leakage into the furnace and accumulates or after shutdown and to insufficient MFT furnace purge unburnt coal or oil accumulation at the end of the tail. 5, soot blower failure, long-term put into operation is not normal. 1 process, when a slight secondary combustion, exhaust gas temperature does not rise within 20 ℃ normal smoking temperature should be checked immediately paragraphs, the combustion site and judge whether the secondary steam soot blowing. (When the exhaust gas temperature rises to 250 ℃) 2, the operation of the back pass and then generating boiler combustion boiler operation should be stopped immediately, immediately stop sending, ID fan and turn off all the smoke and steam soot blowing air damper fire. 3, if the economizer afterburning, until the storage tank level control valve blocking off without pressure, flow rate of feed pump motor start 150t / h Sheung be cooled. 4, air preheater heating surface of the secondary combustion air preheater normal operation, normal operation of the air pre-heater holder; air preheater Jam occurs, the main drive motor and the auxiliary drive motor trip, contact maintenance manual plate moving continuous air preheater rotor. Soot blowing steam into air preheater for extinguishing, into the air preheater for fire extinguishing can not be extinguished. 5, the economizer outlet water temperature close to the inlet temperature (at the economizer secondary combustion), the air preheater inlet gas temperature, exhaust gas temperature, the hot air temperature is lowered to less 80 ℃, each one hole, and the hole is no longer Mars smoke and soot blowing steam stops coming out after water or fire. Open hole inspection manhole and inspection to confirm the secondary combustion goes out, after the flue vent door open to drain water inside the smoke flue opening for ventilation air damper. 6, to be re-combustion is resolved, the flue temperature does not rise and fall when stabilized, before slow regulation of the air, smoke baffle, the necessary air cooling and purging.
