9.Steam from the steam drum is sent to the primary super-heater.

10.Steam is super heated to a high temperature and pressure in the primary super-heaters and then moves to the secondary super-heaters.

11.In the secondary super-heaters steam meets the very hot gases exiting the top of the boiler. The steam is heated to its final temperature and pressure before leaving the boiler as main steam. The main steam is sent to the high pressure steam turbine. The steam turbines drive a generator which produces electricity.

12.Steam exiting the high pressure steam turbine is called cold reheat. It is reheated in the re-heater and sent back to the second steam turbine. By the time the flue gas exits the boiler most of the energy in the coal will be transferred to the water in the boiler. The hot gases are cleaned up before they are sent to a stack. Feed-water is generally supplied by condensed steam from the low pressure steam turbine. Large amounts of cooling water are used to condense this steam into liquid water in the condenser.

April 15 --16 days, ASME joint review by the American Society of Mechanical Engineers group assignment, our company ASME quality control system and demonstrate products on-site audit. After a strict and rigorous audit, the joint review team leader (AIS) announced: "fast Boiler Co., Ltd.-site audit by ASME recommendation issued: power boilers (S) and pressure vessel (U) Certification and Seal"

Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil. Compared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas fired boilers, etc., electricity Heating boiler operation is the most expensive, gas-fired boiler needs to be opened with gas pipeline, then, if there is no natural gas pipeline, but also hope that the operation cost of the boiler is low, only the choice of fuel-fired boiler. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving. After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with coal-fired boiler with the same parameters and capacity, the thermal strength of furnace volume can be doubled. However, in order to reduce the heat load in the combustor zone, the water wall tube in this zone is avoided. Because of the overtemperature, the furnace volume is only reduced by about 1 / 3. Moreover, because the ash content in fuel oil is very little, it will not be slagging on the convection heating surface, so the flue gas temperature at the furnace outlet can be as high as 1300 ℃, and the pitch between tubes on the convection heating surface can be reduced to increase the flue gas flow rate, thus the heat transfer coefficient on the heating surface can be increased. Save heating area and steel. In order to prevent spontaneous combustion of carbon black oil scale on economizers and air preheaters, steam soot blowers should be added to these parts to keep the heating surfaces clean. At the same time, because the fuel oil does not form coke slag, the membrane water-cooled wall can be used to form a micro-positive pressure (500 x 1000 cow / ml). A boiler. It can save the draft fan, only the fan can exhaust the flue gas out of the furnace. If the whole shell of the boiler is made of thick steel plate, it can also be made into a positive pressure (0.3 ~ 0.6 MPA) boiler, which can make the whole structure of the boiler more compact, and is more used in the gas-steam combined cycle generator set.

Boiler maintenance programs Here are some boiler maintenance program: 1, when cleaning the generator, first off the power until completely cooled generator is sweeping .2, once a month to clean the tank to remove dirt and water .3, clear first Turn off oil feed switch, 2-3 times per month .4 clean oil filter, wash the furnace once a year, to remove scale .5 interior pipe wall, frequently wipe generators and burners, fuel tanks and other clean .6 after cleaning if more start, please be dried before being launched. our company has consistently adhered to abide by the contract, thoughtful after-sales business purposes, I will continue to provide better services to you, welcome to visit our factory, and hope to continue to get all the new and old customer support.
