Novel vacuum phase-change boiler

Abstract

The utility model discloses a novel vacuum phase-change boiler, which is main energy source equipment for heating and sanitary water heating at present. The novel vacuum phase-change boiler adopts a horizontal type internal combustion full wet-back three-pass structure, an underneath type large firebox and a reversal chamber, and adopts the main technical proposal that an immersion type front smoke box and an immersion type rear smoke box are arranged in an elliptical housing of the vacuum phase-change boiler to form an immersion type structure of boiler water surrounding the smoke boxes, so that high-temperature flue gas in the front and the rear smoke boxes can be reliably cooled down, the heat of the high-temperature flue gas can be fully absorbed by the boiler water, the heat efficiency of the novel vacuum phase-change boiler can be increased to 94 percent, and the emission of high-temperature flue gas and the pollution to the environment can be reduced. The novel vacuum phase-change boiler disclosed by the utility model has the advantages of more compact structure, saved space in equipment room and material of the front and the rear smoke boxes, and reduced equipment cost.

Description

Technical field: [0001] The invention relates to a novel vacuum phase change boiler, which is the main energy equipment for heating and sanitary hot water. Background technique: [0002] my country's boiler industry began to rise in the 1950s and 1960s. At that time, coal was the mainstay. With the continuous development of the boiler industry, now diesel and natural gas are the main boilers. Its shortcomings are that the overall shape of the traditional fuel (gas) conventional vacuum hot water boiler takes up a lot of space, the heat loss of the front and rear smoke boxes is large, the exhaust temperature is high, the pollutant discharge is serious, the fuel waste is serious, and the thermal efficiency of the boiler is as low as 90%. . During the "Eleventh Five-Year Plan" period of the country, the work policy of energy conservation and emission reduction has been proposed, starting from energy equipment, to meet the requirements of the development of energy equipment in t...
