Reduce the pollution of the diesel generator set

Combustion of diesel generator set if it is not enough is easy to cause air pollution, serious when still can endanger the personal safety of operators and today weifang huaquan power will teach you some tips by improving the fuel to reduce pollution. 
1. The water inlet pipe, air inlet pipe is the main purpose of water absorption of heat and dilute the density of the fuel. When a small amount of water into the combustion chamber and atomization, due to the effect of "micro explosion" of the water vapor to make oil droplets broken into smaller droplets, thus promoting the mixture formation and combustion. Due to the effect of heat of the water in the combustion process can make the maximum combustion temperature is reduced, the water mixed with oil injection can reduce the density of the fuel, is to further reduce the maximum combustion temperature, so the NOx emissions. It is important to note the winter storage tank need to freeze, and demand along with the load size automatically adjust the volume of water. 
2.Emulsified diesel oil, water blending in diesel, emulsified diesel oil, due to its "micro detonation" role, make its fuel atomization is good, and the combustion chamber of the air to form strong turbulence, fuel and air distribution more uniform, the generated reduce carbon smoke. Water vapor water gas reaction also reduce carbon smoke emission. In addition, emulsified diesel oil can decrease the maximum combustion temperature, thus NOx generation decreases.
The above two kinds of practice is to promote through the adjustment of fuel oil burning, burning full after natural emissions of harmful gas becomes less, to reduce environmental pollution, protect the safety of working environment is quite effective. 

Diesel generator set in the cylinder head

Cylinder head is one of the main components of the diesel generator, diesel generator set is mainly composed of diesel engine, synchronous generator, control panel, electrical control equipment and various accessories, its role is largely closed to the upper body, and with the pistons' parts such as cylinder combustion chamber space, as well as the installation of nozzle, intake valve and exhaust valve and rocker arm assembly parts, to ensure the supply high pressure atomized diesel combustion chamber and the inlet and exhaust process smoothly. Water-cooled diesel engine cylinder head is not within the cooling water and lubricating oil channels.
Cylinder head is installed on the top of the cylinder block, from the upper seal cylinder and combustion chamber. It often come in contact with high temperature and high pressure gas, so bear a lot of heat load and mechanical load. Water-cooled engine cylinder cover internal cooling jacket, cooling of the cooling hole of the bottom of cylinder head and cylinder hole. Use of circulating water to cool the combustion chamber high temperature parts, etc. The cylinder head is also equipped with inlet and exhaust valve seat, valve guide hole, used for installation of inlet and exhaust valves, and inlet channel and the exhaust pipe, etc. Gasoline engine has to install the spark plug hole on cylinder head processing, and processing with the installation of fuel injector holes on the diesel cylinder head. Overhead of concave wheel on engine cylinder cover have a concave wheel bearing hole processing, used to install the concave wheel axle. Cylinder head generally USES gray cast iron or alloy cast iron, cast aluminum alloy of good thermal conductivity, is helpful to improve the compression ratio. So aluminium alloy cylinder head in recent years have been used more and more. Cylinder head is part of the combustion chamber, the shape of combustion chamber had a great influence on the engine work, because of the gasoline engine and diesel engine combustion in a different way, the component part of the combustion chamber on cylinder head difference is bigger. Gasoline engine's combustion chamber, mainly on the cylinder head and combustion chamber of diesel engine in the piston at the top of the pit.
I hope this suggest can help you when the diesel generator have fault. I also hope to have the opportunity to cooperate with you.

Generators are commonly used facilities.

The commonly used equipment of form a complete set of generators:  
1.The water jacket heater.
 For water chilling unit, although the use of antifreeze liquid cooling, but in the environmental temperature is below freezing cold area, will still because the liquidity of liquid temperature is too low, the body make generator starts difficult. With water jacket heater, can make the coolant temperature, liquidity enhancement, and rely on the heat transfer to make the body temperature will increase, thus started difficult problems have been solved. 
2.Alternator, control panel moistureproof
If the unit depositing temperature high or low temperature place for a long time, it is recommended to use ac generator and control controller moistureproof. It can lower the temperature of the generator and the control panel, or reduce the electrostatic effect in winter.
3.Start the battery mains charger.
Start the battery charger, electric, can be used in normal charging, to fast or slow start-up battery charging, keep it enough power meet the demand of the next start. This kind of accessories for ready to start the standby generator unit and automation is particularly important.
4.Electronic governor.
Using electronic governor unit different from mechanical speed turbine, the most obvious advantage is to make the steady state frequency adjustment range is small, the speed of the diesel engine than mechanical adjustment type unit stability, make the generator output frequency and voltage fluctuation is small, suitable in some higher requirements on the frequency, voltage load, such as computers, UPS power supply system. In addition, used as a weaver of the units out of efi unit will be required to have electronic governor. 
5.Other.
Other equipment such as:high and low fuel level control switch,grounding fault protection,automatic fuel supplement system,etc., these must be ordered, and mounted by professional personnel.

The matters of attention in the battery used in diesel generator set

Diesel generator set long-term storage battery,before use must give proper charging,in order to ensure the normal capacity of the battery.(can measure the actual capacity of the battery)by hydrometer normal operation and charging can lead to some water is from the battery,which requires rehydration the battery frequently.Before rehyration,first of all,should clean the dirt around the mouth filling,prevent them from falling into the battery box,and then open the mouth filling,adding suitable amount of distilled water or pure water,do not add too full,on the basic of battery pole index plate),otherwise,the battery discharge or charge,the electrolyte inside will be poured out of the overflow .Avoid battery unit start in low temperature,low temperature environment capacity of the battery will not be able to normal output,and discharge for a long time may cause the battery failure (cracking or explosion)spare units periodically yo maintain the battery charging,suggest the user to choose battery was electric.

Master more basic knowledge of the gas turbine generator, buy suitable for generator.

Small conventional gas turbine generator is a typical representative of the large power generation equipment, can provide from 1 to several megawatts of power, can satisfy almost everything including office buildings, hospitals, schools, shops, the demand of the building.
Turbine generator of exhaust gas is an ideal heat source, absorption refrigerating machine is used for cooling, heating and provide sanitary hot water. Because compared with coal gas, the waste gas impurities and sulfur content is low, the second most significant is its high oxygen content, can reach more than 15% and can be used as the combustion air, direct-fired machine on the second combustion.
Gas turbine generators are often used as power rush when load in summer. However, because of the high summer temperatures, resulting in the output of the gas turbine severity shortage, low efficiency. Therefore, lithium bromide refrigerating machine by using turbine exhaust cooling to cool air inlet of turbine generator, can greatly improve the output and efficiency of turbine generator. Has been proved to be a very effective way of energy saving.
Turbine generator usually consists of turbine, gearbox, generator, air intake supercharger and exhaust system.
Turbine generator system according to its process is different, divided into: combined cycle, simple loop and front circulation. Combined cycle is usually produced by recycling waste heat boiler gas turbine exhaust steam, and then drive a steam turbine, or directly provide steam, is a common process of new power plants.
