A large quantity of hot water is needed in hotel for washing or heating, so choosing a good performing and energy saving hot water boiler is vital for hotels. There are several general types of hot water boilers in boiler market, traveling grate type boiler, WNS type hot water boiler, and vacuum hot water boiler. According to different fuel, the boilers includes coal fired hot water boiler, biomass fuel hot water boiler, gas fuel hot water boiler, oil fuel hot water boiler. Every type of boiler has its own advantages.
Traveling grate boiler for hotel
Traveling grate boilers include coal fired hot water boiler and biomass fuel hot water boiler. The boilers can adapt to the requirement of starting and stop, there is good peak regulation, starting fast. Coal fired hot water boiler can burn different kinds of coal with a high efficiency. Biomass fuel hot water boiler can burn biomass fuel such as wood pellet, bagasse, rice husk, and so on, which is more environment friendly and lower cost. But coal fired boiler is more efficient than biomass fuel boiler and the capacity of which is larger than the later one.
WNS type hot water boiler
WNS type hot water boiler can burn gas or oil, which includes oil fired hot water boiler and gas fuel hot water boiler. It is mainly composed of boiler body, connection flue pipes, burner, steam system, instrument, energy saver, condenser. As a packaged fire tube boiler, it has many advantages, such as high efficiency, strong overload, and easy installation and maintenance, which burning light oil, heavy oil, diesel oil, city gas, natural gas, LPG gas, coke oven gas, etc. The advanced design international popular three-pass structure, wet-back structure, whole plate boundary and advanced corrugated furnace design ensure the high efficiency and reliable performance of boiler.
Vacuum hot water boiler
Vacuum hot water boiler is a kind of hot water boiler working under vacuum state, which is no risk of explosion because of no scale inside. This boiler is a new trend in water heating equipment. Its medium circulation system pressure is below the atmospheric pressure, the unit running internal absolute pressure is 0.02 ~ 0.08 MPa, so it is safe in operation. With advanced three-pass and wet back structures, the thermal efficiency can up to 92%.
