The boiler for heating is hot water heating boiler or steam heating boiler?
Generally speaking, whether it is small heating or large central heating, hot water heating hot water boiler is used. At present, the minimum tonnage industrial heating hot water boiler is 1 ton WNS hot water heating hot water boiler. The largest is 160 tons of SZS water pipe hot water heating hot water boiler. Whether large heating hot water boiler or small heating hot water boiler, pollutant discharge is much lower than the national limit, so that customers have no worries about environmental protection for decades. Technical aspect is not worried, Fang quickly launched WNS series and SZS series hot water heating hot water boiler, is worthy of the most efficient heating hot water boiler products.
At present, the heating mode of heating hot water boiler with steam is very few. If the heat source is steam, heat exchanger is also used as intermediary, and hot water is also used as heat dissipation medium to reach the user. If the factory will do this, divide the unnecessary steam while producing the steam and heat the office building or workshop. Let's take a look at the disadvantages of steam heating hot water boiler heating:
1, the temperature rise is too fast, radiator sudden cooling and sudden heat, easy to leak water;
2, the pressure rise is too fast, the radiator is easy to cause metal fatigue, the life is reduced, but also easy to cause the radiator burst;
3, the surface temperature of the radiator is too high, easy to burn people, at the same time, the indoor meteorological conditions are not good, indoor dust decomposes above the radiator, resulting in blackening of the wall above the radiator;
4, if the heating pipe effect before heating steam supply is not good, the steam supply will cause water hammer, the water in the radiator will form a water hammer under the impact of steam, impact the radiator and pipe, loud noise, affect the rest at night, but also damage the radiator and pipe;
5. The water in the heating hot water boiler absorbs the heat emitted by the fuel, and the water molecules become steam and absorb part of the heat, resulting in energy waste. To sum up, steam heating is not economical, and there are many hidden dangers, so in recent years, steam heating hot water boiler as heat source is less and less.
