Plate-fin heat exchanger for gas heater

Abstract: The invention discloses a plate-fin heat exchanger for a gas heater, comprising a core body, seal heads, an inlet connection pipe and an outlet connection pipe, wherein the core body comprises a plurality of flue gas channels and sanitary water channels which are divided by partition plates in a rectangular cavity and are alternately connected; in the flue gas channel, flue gas side fins are arranged between two metal partition plates and are longitudinally arrayed, and the left and the right sides of each flue gas side fin are sealed by sealing tapes; in the sanitary water channel, water side fins are arranged between two metal partition plates and are transversely arrayed, the upper and the lower sides of each water side fin are sealed by sealing tapes, the left and the right ends of each water side fin are respectively communicated with the two seal heads, the seal heads at both sides are respectively connected with the inlet connection pipe and the outlet connection pipe of sanitary water, and the flue gas side fins and the water side fins are in continuous groove structures The gas-water exchanger of the gas heater has high heat exchange efficiency, reduces the consumption of gas and achieves the purposes of saving energy, reducing device size and reducing production cost

Gas removal equipment, gas removal vessel, and method for removing gas from tank

Abstract: PROBLEM TO BE SOLVED: To perform a procedure for removing gas in a fuel gas tank without causing problems such as securing of an installation space and cost rise.SOLUTION: By equipping a vessel (100) with gas removal equipment (10) provided with a gas compression unit (20), a gas heater unit (30), a gas combustion unit (40), and an inert gas supply unit (50), fuel gas in a tank (110) is removed even in the vessel (100) not provided with devices for performing a procedure for removing gas.

Abstract: The utility model discloses a minimum discharge purifier of municipal solid waste incineration flue gas, the device includes the flue gas reflux unit, SNCR denitrification facility, the semidry method reaction tower, lime water preparation and atomizing injection apparatus, active carbon and slaked lime dry powder injection apparatus, bag collector, wet -type deacidification tower, 1# flue gas gas gas heater, 2# flue gas gas gas heater (2#GGH), steam gas gas heater (SGH), SCR denitrification facility, draught fan and chimney. Through 1#GGH, 2#GGH, SGH heating, remaining NOx and dioxin in the further desorption flue gas of reentrant SCR reactor, pollutant levels finally are superior to the 2000 emission standard of european union, realization minimum discharge.

Direct-fired heater

Abstract: A combustion system for a portable forced air heater having two frusta-conical sections attached to a circular burner tube, wherein each frusta-conical section has pre-determined vent hole patterns that allow the gas heater to have a variable burn rate.

Fuel storage and supply system for LNG (liquefied natural gas) power ship

Abstract: The utility model relates to a fuel storage and supply system for an LNG (liquefied natural gas) power ship. The fuel storage and supply system comprises two LNG storage tanks, two buffer tanks, a high-pressure pump, a high-pressure vaporizer, a low-pressure vaporizer, a cold energy utilization device, a gas heater, a reliquefaction device, an auxiliary boiler and an exhaust boiler, wherein the two LNG storage tanks are cascaded and transport LNG to the first buffer tank and the low-pressure vaporizer via an LNG immersed pump inside the LNG storage tank; the first buffer tank is connected with a cold energy utilization heat exchanger via the high-pressure pump, and the cold energy utilization heat exchanger and the cold energy utilization device form a coolant circulating system; the cold energy utilization heat exchanger is connected with the high-pressure vaporizer; the high-pressure vaporizer is connected with the second buffer tank; the low-pressure vaporizer is connected with a dual-fuel diesel generator; and the second buffer tank is connected with a dual-fuel main diesel. By the fuel storage and supply system, the problems of high pressure of BOG gas in the LNG storage tank during long-time mooring and ship repair and methane discharge caused by high pressure of the storage tank are solved.
