About the advantages of gas-steam oven gas is mainly reflected in what way in recent years, with the continuous development of the exhaust boiler system for steam turbines industry, a variety of devices including gas, including gas-steam oven has been further developed and applied. We know that the production of each device can be widely used. It has its own advantages, the main advantage of what gas furnace gas and steam are we talking about today? According to reports, the gas can understand that gas-steam oven does not require the accumulation of ash, thus eliminating area. When the gas for a fuel delivery gas steam oven, other auxiliary machines less, low-power, continuous operation time is short, and therefore at a high level, saving electricity. Production of heat transfer oil boiler. Others because the gas furnace gas and steam will now run out of dust and pollution, natural gas is used as a clean energy source. In the Gas Gas steam oven operation, no pollution, and it is easy to achieve. Nightly environmental needs. Daily use of gas gas steam oven needs maintenance. When not in use the boiler, should carry out maintenance and maintenance. This will not only extend life, but also can reduce the use of various problems arising in the process. First of all, when not in use boiler, heat transfer oil to be discharged of all internal, because if there is oil, the quality will change. If a leak occurs, it will affect the surrounding environment, and needs to be cleaned after release. Clean the inside of the boiler to maintain and keep other impurities. Secondly, regularly check the various components of the gas oil furnace to see if there are loose. After maintenance, the boiler can be stored, can be used directly in the next use, not other problems. Xiao Bian remind you, after using a gas furnace gas and steam for some time, the loss will occur. If the loss is too large, it will affect their use, particularly in certain connections and transmission loss larger. Add lubricant to reduce the loss of these components and more stable performance of the boiler.

Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
How how electric steam exhaust boiler system for steam turbines maintenance electric steam boiler maintenance 1, boiler maintenance, must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, electric steam boilers stop running long time, turn off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, with a slow fire the burner drying pot (burning time not too long, to avoid damage to the boiler), then all of the drained gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve.
Boiler. - Exhaust gas boiler, economiser An exhaust gas heat exchanger is a row of tube banks circulted by feed water over which the exhaust gases from main diesel engine flow. A boiler drum is required for steam generation and separation to take place. For this purpose, the drum of an auxiliary boiler is usually used. See also Exhaust gasLearn More
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).Learn More

The fuel is fired in a boiler which converts the heat released from combustion to steam at high pressure and temperature. This steam is then expanded through a turbine for generation of electrical power. Exhaust steam from the turbine is condensed in a heat exchanger and then returned via the feed pumps to the boiler.Learn More
Diesel engine builders have developed engines with greater powers in response to the shipowners demand and also in competition with steam turbines, for propulsion. Diesels are now used almost exclusively for modern ships. Only for liquefied gas carriers where the gas boil-off can be burned in the boilers, are steam turbines still being installed.Learn More
