Hot water boiler is a kind of thermal equipment that uses natural gas, oil and biomass as fuel to heat water to the rated temperature. It is widely used for heating, bathing and domestic hot water in hotels, schools, hotels, communities and other enterprises and institutions. Generally, pressurized hot water boiler is widely used, so what does pressure-bearing hot water boiler mean?
In a pressure-bearing hot water boiler, the meaning of pressure is that the internal pressure of the boil...
The fuel of gas boiler is mainly natural gas, petroleum gas, gas, etc. The air energy water heater is powered by electric power and air energy to maintain the operation of the machine.
Because gas-fired hot water heating boiler is used for central heating, after the boiler is ignited, it needs to go through a series of processes such as furnace heating, low-temperature operation, heat exchange and so on, to gradually heat up the central heating. After ignition of gas-fired hot water heating boiler, furnace heating is a necessary preparation work at the initial stage of heating every year, and this process takes about 3-5 days to complete.
Many people will consider the heating efficiency and heating area when choosing and using boiler equipment. In fact, how many square meters a ton of hot water boiler can heat has a certain relationship with the type and capacity of the equipment.
Generally speaking, the heat to be absorbed by 1kg of water is 1kcal for every 1℃ increase, it is concluded that the heat supply of 1 ton (0.7MW) boiler is 600,000 kcal. Therefore, how much boiler is needed to heat 20 tons of water from 15℃ to 40℃ for ...
Gas-fired boiler products used in different industries will be different. With the increasingly stringent environmental protection policies issued by the state in recent years, gas-fired boilers are widely used in all walks of life. The quotation of different configurations of gas-fired boiler varies greatly, and the quotation of 3-ton gas-fired boiler does not have a fixed amount, because the quotation of 3-ton gas-fired boiler system is composed of boiler body price and auxiliary equipment pri...
As we all know, the transportation cost is generally related to the weight of the boiler, so how much does a 4-ton boiler weigh? How much steel does it contain? According to the fuel, 4-ton boilers are divided into 4-ton gas-fired boilers and 4-ton coal-fired and biomass-fired boilers. The amount of steel used for small-scale coal-fired and biomass-fired boilers is generally 5-7 times of the boiler output (excluding the front and rear arches), and about 25 tons for 4-ton boilers.
As a kind of special equipment, industrial boiler is special and complex. Complete inspection can ensure the safety operation of the boiler.
The external inspection of the boiler is generally conducted once a year, the internal inspection is generally conducted once every two years, and the hydrostatic test is generally conducted once every six years.
For boilers that cannot be inspected internally, a water pressure test should be conducted every three years. The internal ...
There are many valves commonly used in atmospheric gas-fired boilers, including gate valves and stop valves of main steam valves, water supply valves, check valves, exhaust valves, etc.
When the water pump is turned on, the pressure signal is transmitted to the on-off valve of the atmospheric gas-fired boiler through the pressure pipe, the valve is opened, and the water circulation is carried out. When the water pump stops, the pressure drops, and the on-off valve is closed slowly to av...
