How Wanning miniaturization steam boiler with steam turbine generator to buy a lot of companies actually steam boiler supply and demand on the number of small lot, so this kind of miniaturization, also known as steam boiler steam generator, the burner according to the water temperature reaches 100 degrees, it will rapid formation of steam, thereby leading to the manufacturing needs of the user. This is what we often want to explore downsizing steam boiler. Thus how do we buy steam boilers, in fact, we are generally able to purchase fuel from their own advantages and steam boilers, and some people need to use their own power, we buy that is electrically powered steam boilers can greatly reduce own costs. If the size is very large steam boilers, auxiliary gas pipeline through nor can purchase a biomass steam boiler, can reduce fuel costs, according to their manufacturing biomass, can quickly reach the combustion of fuel. If the steam supply and demand value is very small, you can buy often said steam generator to reach a big problem with a small cost!

Gas-fired boiler with steam turbine generator or electric boiler which is good?To compare the two kinds of boilers better, we need to understand the advantages and disadvantages of the boilers. The advantages of electric boiler are: 1, high thermal efficiency: can meet the requirements of winter heating in all regions; 2, electric boiler is beneficial to environmental protection: no leakage, low noise, no pollution; 3, convenient use: automatic control, no special guard; Intelligent thermostat automatic control, flexible and convenient use, indoor temperature can be set by their own needs, start and close the machine can be controlled by the computer. The disadvantages of electric boilers are: 1. The operation cost is high, is gas-fired boiler 2 times, is gas-fired boiler 4 times. 2. The boiler must be supplied with three-phase electricity at 380 volts. If there is a power loss or power outage, there is no alternative. Seriously affect the normal production and operation of enterprise units. The advantages of gas-fired boiler are as follows: (1) the thermal efficiency is as high as 90%: it can meet the requirements of hot water heating in all regions; 2. Gas-fired boilers are conducive to the national strategy of energy conservation and emission reduction, collect agricultural and forestry wastes such as straws that are directly burned and cause pollution, and produce gas granular fuels through processing, which can bring benefits to farmers. Greatly reduce emissions of pollutants from exhaust gases. 3, convenient use: full automatic control, no special guard; flexible and convenient use, 4, gas fuel is similar to coal gasification combustion and suspension combustion state, flue gas stays in the high temperature furnace for a long time, through the use of the gas fuel is similar to the coal gasification combustion and suspension combustion state. Multiple air distribution, anaerobic, upper feed, lower fire, lower suction combustion, full combustion, high fuel utilization rate, no black smoke. 5, using the furnace dust removal device, with which the original concentration of boiler dust emission is low, can not use chimneys. 6, continuous fuel combustion, stable operating conditions, do not be affected by the addition of fuel or stabbing, can ensure output. 7, the fuel source is extensive, the cost is low. Not limited by the season, can be used throughout the year. The gas-fired boiler is half of the gas-fired boiler, 1/3 of the oil-fired boiler and 1/4 of the electric boiler. 9. Fangkuai gas-fired boiler In a modular design, each system uses one furnace body, two combustion heads or two furnace heads, one burner head 300000 truck in summer, and two burner heads 600000 truck when heating in autumn. When the coldest in winter, you can open four burning stoves 80-1.8 million truck, that is, the heating boiler only uses 300000 calories in summer, 600000 calories in autumn, 1.8 million calories in winter, one machine multi-use. In this way, customers do not need to invest in two sets of equipment systems, greatly reducing their first investment costs and operating costs. The disadvantages of gas-fired boilers are: 1. Need free space or The warehouse is used for storing gas particle fuel; 2. Blower induced fan and other accessories need 220 volts, affected by power outages, but diesel engine can be used to power boiler accessories. Keep the boiler running as usual! Summary: gas-fired boilers and electric boilers are environment-friendly boilers, automatic control, can adapt to various areas, the price of raw materials is stable; but the operating costs of electric boilers are too high to be affordable by ordinary enterprise units. Too much reliance on electricity, once there is a power outage, will seriously affect the normal production and operation of enterprises. Gas-fired boiler is different, in all clean energy boilers, its comprehensive operation The lowest cost. Although electric drive boiler accessories are needed in ordinary operation, the dependence on electricity is not great, and diesel generator can be used to operate power driven boiler fittings in the state of blackout. Because gas particles fuel ignition point, is not flammable, so even if the stack in the aisle side also does not matter. Overall: gas-fired boiler is better, can save a lot of operating costs for enterprises, economic, practical and environmental protection, and its small shortcomings easy to solve the impact of little.

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.
