dhl series coal fired steam boiler

Hot water boiler and a traditional old-fashioned coal-fired boiler is how to deal with water shortages? Machine in use for some time there will be this or that problem, a serious delay the progress of work, causing great inconvenience to the people, such as water shortages, the question arises, hot water boilers and water shortage in the traditional old-fashioned coal-fired boilers It is how to deal with? Electric dhl series coal fired steam boiler how to deal with water shortages: water level proofread each water level indicated by the right to judge whether the electric steam boiler water. In the electric boiler can not be determined when full of water or water vapor, can turn on the water faucet open water level, water flows out of the pot if not, indicating that water scarcity is an accident, otherwise it is full of water accidents. For the embodiment allows a small electric steam boiler waters operation, water may be called first, determines the electric steam boiler is mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and fire community large electric steam boiler. Otherwise it can not be called electric steam boiler water, because it will delay the time of the incident electric steam boiler water treatment, the worsening of the situation. When a slight electric steam boiler water, should reduce the fuel and air, the combustion decreased, and electric steam boiler feed water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then check the electric steam boilers there is no unusual circumstances, after confirmation by the normal operation can resume electric steam boilers. When electric steam boilers severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of electric steam boiler water shortages, interrupted several times with water, each time a small amount of water replenishment way to cover up the accident electric steam boilers. This practice is very dangerous. If electric steam boilers are also less severe water shortage will cause biomass boiler leaks. If electric steam boiler water can cause serious electric steam boiler explosion. Only natural ventilation and cooling in electric steam boiler pot temperature dropped to below 70 ℃, water only slowly. Electric steam boiler for the water to normal level after thorough examination, no abnormal situation in order to re-start ignition, electric steam boilers to resume operation. Traditional old-fashioned coal-fired boiler using coal, gas, fuel oil and other fuel, these fuels are non-reusable primary energy, the future price will be higher. And the shortcomings of the traditional old-fashioned coal-fired heating methods are also caused by incomplete combustion, incomplete combustion can cause a lot of heat from the flue gas discharge out together, so it will cause energy losses. Boiler not only save electricity, but also saves time and effort, not the traditional coal-fired boiler heating boiler released by carbon dioxide, toxic gases, dust and other harmful substances, so users do not need to clean up, so it can save a large sum of maintenance cost.

The reason gas dhl series coal fired steam boiler flame of abnormal phenomena and processing method. Flameout for the following reasons: 1. Auxiliary trip or power interruption. 2. boiler combustion instability. 3. When the load is too low, due to the sudden drop in load, ignition energy mill will be lost or the combustion is automatically stopped. 4. mutation coal, low volatile or low calorific value. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. 5, the automatic combustion flame detectors or failure resulting in failure to trip mill. 6. The furnace wall or squib serious improper boiler soot-blowing operation, a large amount of steam into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a substantial amount of fuel reduction or interruption. A large amount of water or impurities in the fuel oil gun clogging, or atomized vapor pressure is too low. Second, the phenomenon: 1, furnace pressure was significantly higher, flameless furnace flame monitoring CRT display. Pit of fire no fire. BTG MFT alarm window alarm indicator lights. 2. The unit load is reduced, steam flow drops rapidly, and the temperature of each section of the working medium vapor pressure decrease, a sharp increase in oxygen index. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 3. Treatment: 1. If you refuse to run MFT protection, emergency stop should be handled according to the situation and stop the supply of fuel. 2.2. Identify the cause of stalling, and try to eliminate it. Conduct a comprehensive inspection of the boiler, and to confirm proper before the device is restarted.

The fast boiler related personnel monitoring center, started after the boiler, the boiler pressure, exhaust gas temperature and other sensors will automatically collecting various kinds of boiler operation data and real-time transmission through the mobile network to a remote monitoring center located at the headquarters of the fast boiler ; operating data once abnormal or deviation, the monitoring center monitoring personnel can detect and organize experts to analyze and issue alerts and corrective measures.

Check Item item hot water boiler hot water boiler comprising a boiler inspection and checking internal use preparations, checking in the furnace and the flue, the boiler attachment check, check automatic control system, the secondary device, check the combustion device, the auxiliary heat check the surface of the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect and causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling. It is fed out of the hot water boiler heat equivalent to a mass per hour (usually expressed in tons) in water was heated from 20 ℃ and heat output of all vaporized into a dhl series coal fired steam boiler water absorbed three expressions, in tons) water from 20 ℃ heated and vaporized into all heat absorbed by the steam boiler it is fed out of the hot water heat equivalent to a mass per hour (i.e. typically kcal / hr (kcal / h), tonnes / hour (t / h ), megawatt (MW). (1) kcal / h is in metric units of expression, which represents the heat of hot water boiler fed out per hour. (2) t t borrowed steamed steam boiler popular argument, ( 3) megawatts (MW) is the international system of units unit of power, the basic unit is W (1MW = 106W). this expression formal documents should be used.
