How much is a steam generator
Summary: With the implementation of national environmental protection policies, energy-saving and environmentally friendly steam generator gradually replace the boiler, there are many steam generators on the market, the price varies greatly, from a few thousand to tens of thousands, and even on hundreds of thousands. Many domestic industries in the choice of steam generator, the price as a selection factor, in fact, this approach is very wrong. So how to buy a steam generator? Here to understand. First, how much a steam generator

Generally a single steam generator price of a few thousand to tens of thousands of dollars, or even hundreds of thousands of dollars, but the specific amount of money also needs to be combined with the size of the equipment, temperature and pressure high and low, the type of fuel, the quality of the material and the configuration of the components of a variety of conditions to see the whole picture.

1, equipment size

Steam generator rated evaporation or rated power, the larger the purchase of equipment, the more money spent, and vice versa, the cheaper.

2, the temperature and pressure of the high and low

170 ° C is the conventional temperature of the steam generator, low generally around 110 ° C, high nearly 1000 ° C, different temperatures tend to correspond to different pressures, the higher the temperature, the greater the need for pressure, the higher the price of the purchase.

3, fuel

Different types of steam generators require different fuels, such as electric heating, fuel oil, gas, burning biomass pellets, burning coal, etc., in general, the same evaporation capacity of the steam generator fuel oil and gas equipment structure is complex, the purchase price is relatively high, followed by electrically heated steam generator, burning biomass and coal price is low, but the pollution emission is not good to control. The application surface is narrow.

4, material quality and component configuration

Steam generator has a high and low end of the difference between the quality of the raw materials used and the configuration of the components are also different, such as the use of stainless steel liner steam generator is more expensive than conventional steam generator.

So, how much a steam generator and can not be said exactly, can affect the price of the steam generator factors roughly contain the above points, you can refer to when buying.

Two, how to buy a steam generator

1, look at the thermal efficiency

The steam generator on the market is roughly divided into: biomass, gas, fuel oil, electric heating, etc. These categories, we buy the most concerned about the steam generator is the same size whether the full amount of steam, according to the various types of product comparison, which can be as high as 99% of the thermal efficiency of the gas.

2, whether the economic use of the cost

(1) electric steam generator to electricity as an energy source, the current general price of electricity for urban residents: 0.52 yuan -0.62 yuan a power, industrial electricity is a little more expensive, the price: 0.86-1.80 yuan a power, according to the calculation of a dollar a power, electric steam generator to produce a ton of steam needs 720KW/H, that is, 720 yuan. 720 dollars.

(2) gas steam generator to natural gas or liquefied petroleum gas as a fuel, the normal gas steam generator needs to consume 85 cubic meters of natural gas per ton of steam, according to a cubic meter of natural gas for $ 4, need 340 yuan, and the heat King full pre-mixed condensing gas steam generator only 75 cubic meters of gas, to produce a ton of steam needs 300 yuan.

(3) oil-fired steam generator to diesel fuel, oil-fired steam generator needs to consume 60 liters of diesel fuel to produce one ton of steam, according to a liter of diesel fuel at $6, it costs $360.

(4) biomass steam generator to biomass pellets as fuel, the use of cheaper, but NOX is higher, the future will be strictly controlled. Biomass steam generator needs to consume 150 kilograms of pellets for each ton of steam generated, according to the calculation of 1 kilogram 1 dollar, need 150 dollars. The above prices are subject to actual occurrence.

In summary, the cost of each ton of steam generated, where the cost of electricity is the highest, the cost of biomass is the lowest.

3, whether it meets the new boiler exemption standards

Most steam generators on the market over 30L water volume, does not meet the new boiler exemption policy, there are major safety hazards. In the purchase, it is recommended to choose the water capacity & lt; 30L steam generator, does not belong to the special equipment, the state exempt from inspection.

4, steam generator brand

In order to ensure safety in the use of the process, the steam generator in the manufacture and installation are subject to strict policy control, some small-scale steam generator factory in the manufacture of jerry-built above, or in the after-sales standard is not perfect, may lead to steam generator in operation when some failures, be sure to select the steam generator guaranteed! Manufacturers to ensure that the steam generator can run safely for a long time.
