oil fired steam generator for sale
Combined heat and power (CHP) introduction
Cogeneration, refers to the heat and power plant in the same joint together, shorted as CHP (combined heat and power). CHP plants have been ordinary waste heat to be utilized to provide cheap heating heat for industrial and household use, which can greatly improve the thermal efficiency. Typically thermal power, its efficiency is about 30 to 35%. This means that for every 1 mega-joule energy output, there are two mega-joules of heat wasted. This part of the heat of re-used to heat water, fully meet the heating needs of the plant and the residential area near the plant. CHP usually drive a steam turbine generator, and the exhaust heat is used to complement the existing boiler plant, the total efficiency of up to 80%.
7) Steam from the steam drum is sent to the primary superheater.
8) Steam is super heated to a high temperature and pressure in the primary superheaters and then moves to the secondary superheaters.
9) In the secondary superheaters 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.
10)Steam exiting the high pressure steam turbine is called cold reheat. It is reheated in the reheater and sent back to the second steam turbine.
Throat automatic electric supply system of the fired steam generator for sale, steam drying steady flow supplied to the user. When the water into the tank, the power switch, controlled by the drive signal, high temperature solenoid valve is opened, the pump work, is injected through the check valve furnace. When the solenoid valve, the check valve is clogged or damaged, the water pressure reaches a certain overpressure valve through overflow back into the tank, to protect the pump. When the tank without water or residual air in the pump piping, air not only into the water, as long as the rapid exhaust through the exhaust valve until the discharge water, close the exhaust valve, the pump will function. The main water supply system component is the pump, they use a multi-stage vortex pump of higher pressure and a larger flow rate, using a small part of the diaphragm pump or a vane pump. Stainless steel mechanical float level controller for generator furnace large volume, the working pressure is not stable, but easy to washable, maintenance and repair. Furnace boiler body generally use special seamless steel pipe, elongated upright. Most electric heating system or a heating tube used in a root canal curvature combination of stainless steel heating, while the surface load is generally about 20 W / cm. Due to the higher pressure and temperature when the generator is working properly, the safety protection system in the long run can make it safe, reliable and efficient. It is generally produced using high strength copper alloy valve, check valve, an exhaust valve, implement three protection. Some products also increased the water level in the glass tube protection device, increasing the user's sense of security. Product choice points: Electric steam boiler main control parameter is selected nominal evaporation, thermal efficiency of the boiler design, the rated steam pressure, the rated input electric power and the like. Use of electric steam boilers should meet the requirements of national and local restrictions related standards, norms. Using the selection of appropriate thermal storage electric boiler system, i.e., when the low electric power, the heat stored in the heat storage medium; at peak power stage, the heat stored in the heat storage medium released for users. It features electric boiler thermal storage system is different for peak electricity prices, operating cost savings for the user, and by peak load shifting power grid, good for grid security, economic operation. Electric steam boiler with the steam accumulator reservoir may be higher, the higher the heat of the argument, but the high electric steam boiler plus steam accumulator system cost, operation and management require a higher level, and therefore, do not ask for the heating parameters heating, living, air conditioning system, electric steam boiler plus steam accumulator system is rarely used. Electric power distribution chamber should be supplied directly to the boiler, the discharge conveyor can be used, or a metal cable. Determining the load and the number of electric boiler, boiler room should be combined transformer capacity equipped with comprehensive consideration. Many boilers can share a transformer, but not multiple transformers to supply a common boiler. Taipower power single steam boiler should not be greater than 2.4MW. Steam boiler feed water pot outside the general chemical water treatment, water quality should be specified. Installation and construction, installation points, boilers and auxiliary equipment, water treatment equipment should meet the technical requirements of the device manufacturer. Equipment foundation must be the arrival of equipment and after verification and design drawings before construction. The highest point of the pipeline deflation, the lowest point turn on the water. Acceptance pressure test after the pipe installation. Electric boiler room should all be grounded electrical equipment and heat storing devices. Precautions: power supply voltage can not exceed ± 5% of the rated voltage. Choice of fuel kerosene, diesel oil, do not use gasoline and heavy oil; when winter temperatures below 0 degrees, 0 # diesel oil are often solidification phenomena, not to use, it is best to use -10 # diesel or kerosene. You must be ground wire construction requirements:! Strength of electrical wiring must be separated, such as walking level sensors, pressure sensors and other electrical control of strong and weak lines output lines of the controller separately. When the installation site, should not wear in the same PVC pipe as arranged in parallel should be held at least 200mm intervals. Ban placed around the boiler gasoline, bananas, water and other inflammable and explosive materials. When using a gas boiler-room electronic leak detection alarm device should be installed to prevent accidents.
Central heating hot water boilers for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.
