Rated evaporation represents the size of the equipment. Generally speaking, the larger the rated evaporation of small steam generators of the same brand, model and configuration, the more money it will cost to buy them.
Equipment configuration includes how high the temperature and pressure of outlet steam can reach, the quality of each component, and how to control pollution discharge. For example, a small steam generator with higher temperature and pressure needs more exquisite casting technology, Excellence and repeated calibration and debugging, and the price of such steam equipment is of course higher.
Fuel forms of small steam generators include electricity, natural gas, liquefied gas, diesel oil and biomass particles. Different fuels need different combustion heating devices, which are simple or complex, which involves the configuration and production process of steam generator components. Of course, the more sophisticated the steam equipment, the higher the price.
