Gas heater with prevent frostbite and preheat function

Abstract: The utility model relates to an in gas heater with prevent frostbite and preheat function, its moderate temperature examine and know that ware, water pump and heat exchange line locate the casing, water supply connector, water return joint and water connectors locate on the casing and expose outside the casing, water return joint and water supply connector are connected simultaneously to heat exchange line one end, other end connection water connectors, water connectors loops through the outlet pipe way and water return joint is connected to the return water pipeline, the water supply connector is passed through water intake pipe and is connected with outside water source, the temperature is examined and is known that the ware detects near the temperature in water supply connector, controlling means examines the operation of knowing the ware feedack and coming the control pump according to the temperature, the water pump is used for driving the circulation of outlet pipe way, heat exchange line and return water pipeline normal water. The utility model discloses utilize return water pipeline, heat exchange line and outlet pipe way to constitute the preheating circulation return circuit, utilize circulation circuit to carry out water route circulation or low -temperature combustion to reach the function of preheating and protecting the organism not freeze.

Method for regulating gaseous temperature in stack gas desulfurization

Abstract: PURPOSE:To improve the corrosion resistance of a titled device without reducing heat medium temp. as far as possible despite the generation of load fluctuations by installing a heat medium heater 3 between the heat medium pipings after elevating temp. with an untreated gas side gas-gas heater. CONSTITUTION:An untreated gas is increased of pressure with a waste gas fan 33 through a gas duct 39, and enters an untreated gas side gas-gas heater 1 by passing through a gas duct 10. In the heater 1, the untreated gas heats the heat medium fed by a heat medium pump 5 in a heat transmitting pipe 28, and enters a cooling tower 34 and absorption tower 35 through a gas duct 11, whereby it is made into a treated gas. Thence, the treated gas is further heated with a heat medium heater 3 in a treated gas side gas-gas heater 2, and is heated by the heat medium introduced into a heat transmitting pipe 29 through a heat medium piping 24, then this gas enters a steam gas heater 36 through a gas duct 13, and is further heated by the steam flowing in a heat transmitting pipe 38. The gas is then released into the atmosphere from a stack 37 through a gas duct 41.

Portable gas heater with gas bottle container - which has trolley for IR radiator, usable for food serving

Abstract: The gas heater (10) has a housing (50,52,56,60), accommodating a gas bottle (48), and a support (16,30,20) for an IR heater (14). The housing forms a food serving device, partic. a trolley (12). There is pref. a flat top plate (56) extending horizontally and protruding beyond the housing and incorporating a handle (72). The heater support can be adjustable, and additional equipment for food preparation can be included (82,86). ADVANTAGE - Compact design for food serving.

Flow adjuster of gas water heater

Abstract: A controlling device of water flow applied in the gas heater comprises a water valve body and an electro pneumatic valve, wherein, the water valve is provided with inlet pipe and outlet pipe, of which is/ is not communicated with each other. The utility model also comprises waterflow rotor component and a Hall sensor. The waterflow rotor component is arranged inside the inlet pipe and the Hall sensor is positioned correspondently to the waterflow rotor component on the water valve body which is provided with a plurality of separated housings and bypassing water pipes; the plurality of separated housings is directly communicated with the inlet pipe and is communicated with the outlet pipe and the bypassing pipe through the electro pneumatic valve on the separated housing. The utility model has the advantages of effective realization of automatic detection of water flow, automatic control of water flow, increasing the security and pleasance of using the gas heater and so on. The utility model also has the advantage of automatic bypassing of water (aiming at reducing the temperature rise of the water), therefore, the burn by hot water can be prevented.

Duct structure of waste gas desulfurizer

Abstract: PROBLEM TO BE SOLVED: To prevent the problem of entering side waste gas leaking to a stack by simple duct structure. SOLUTION: In duct structure of a waste gas desulfurizer in which after entering side waste gas 4 from a waste gas feeding duct 6 is led to a gas-gas heater through an inlet damper, it is led to a desulfurizer to be desulfurized and after going side waste gas 4a from the desulfurizer is led to the gas heater, it is discharged to a stack by a waste gas duct 10a through an outlet damper, the waste gas feeding duct 6 and the discharge duct 10a are connected by a bypass duct 19 provided with two bending parts 16 and one contraction part 18, and in the connecting part of the bypass duct 19 in the waste gas feeding duct 6, a gas straightening part 22 for heightening a flow of the entering side gas 4 in the waste gas feeding duct 6 is installed.
