The invention relates to an oil-or-gas water tube vacuum water heating unit. The vacuum water heating unit comprises a hearth and a convection heating surface region which are defined by membrane walls respectively. The hearth and the convection heating surface region are separated by a separation-wall membrane wall, and a burner is arranged in the hearth. A smoke channel is formed in the convection heating surface region, a smoke inlet is formed in the front end of the smoke channel corresponding to the hearth, and a smoke outlet is formed in the tail end of the smoke channel corresponding to the hearth. A boiler drum is arranged above the smoke channel, a rectangular header is arranged on the lower portion, and convection tube bundles are arranged between the boiler drum and the rectangular header. An underwater hole plate is arranged on the inner wall of the bottom of the boiler drum and covers all connection ports of the convection tube bundles and the boiler, a steam-water separator for producing heat medium steam is arranged in the boiler drum, and heat exchange tubes and a heat exchange header are arranged above the steam-water separator to form a steam-water heat exchange region. A top gas collection unit and a vacuumizing steam exhaust unit are arranged on the boiler drum corresponding to the steam-water heat exchange region. The vacuum water heating unit is simple in structure, compact in arrangement and capable of guaranteeing enlarging design of the water tube vacuum water heating unit.
Description
technical field [0001] The invention belongs to the technical field of hot water boilers, and in particular relates to a water tube vacuum hot water unit. Background technique [0002] At present, my country's energy consumption per unit of output value is 2.3 times that of the world's average level, and the unit energy consumption of major energy-consuming products is 40% higher than that of advanced foreign countries; my country's energy consumption per dollar of GNP created is 4.97 times that of Germany and 4.43 times that of Japan. It is 2.1 times that of the United States and 1.65 times that of India. This is one of the important reasons for the rising cost of enterprises and poor economic benefits. According to the survey, the consumption of energy and raw materials of industrial products in my country accounts for about 75% of the production cost of enterprises, and if it is reduced by one percentage point, more than 10 billion yuan of benefits can be obtained.
