Fuel oil and gas pipe pipe-in-pipe three-pass vertical steam generator

Abstract

The invention discloses a fuel oil and gas pipe pipe-in-pipe three-pass vertical steam generator, and relates to the technical field of fuel oil and gas boilers. The fuel oil and gas pipe pipe-in-pipethree-pass vertical steam generator comprises a base, a steam-water separator, a furnace pipe, a combustor, a steam box, a lower smoke box, a sleeve inner pipe, a steam conveying pipe, a furnace pipeouter sleeve and a sleeve outer pipe. The bottom of the lower smoke box is fixedly connected with the top of the base, and a fire outlet of the combustor communicates with the top of the surface of the furnace pipe. According to the fuel oil and gas pipe pipe-in-pipe three-pass vertical steam generator, the water capacity can be small, the heating area can be large, the effective water capacity can be effectively controlled within 30 L, steam is generated within 2 min, saturated steam is generated within 5 min, and the steam can be evaporated 100%; energy and time are saved, and the generation efficiency of the steam of an electric boiler is improved; meanwhile, the explosions are avoided forever, good safety performance is achieved, and the utilization rate of heat energy is greatly increased; and heat supply of the boiler is guaranteed, the heat absorption efficiency of the boiler is improved, the exhaust smoke temperature is reduced, and pollutant emissions are reduced.

Description

technical field [0001] The invention relates to the technical field of fuel gas boilers, in particular to a tube-in-pipe three-return vertical steam generator for fuel gas. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire. Furnace refers to the place where fuel is burned. Boiler includes two parts: pot and furnace. The pot is a pressurized part containing water and steam, which heats, vaporizes and separates steam and water. Furnace is a place for fuel combustion or other thermal energy release. , There are combustion equipment, combustion chamber, furnace and heat release flue, etc. The heat conversion process is carried out between the pot and the furnace. The int...
