Evaluation of Water Heating Systems Through Life Cycle Assessment

Abstract: The aim of this study is to evaluate water-heating systems through Life Cycle Assessment (LCA). The method involves the application of LCA for the analysis of the global warming potential of water-heating systems that use electricity, gas or solar energy as input. The analysis was performed for a single-family house and also for a four-storey residential building located in three cities in Brazil. The SimaPro computer programme, widely used in the global market when it comes to LCA, was used. The results showed that for the single-family house, the electric shower head is the option that causes less environmental impact for all cities, followed by the solar heater with electric backup and, finally, gas heater with continuous flow. As for the four-storey residential building, the solar heater was the best alternative, followed by the electric shower head, electric boiler, gas heater with continuous flow and, finally, gas boiler. The use phase was responsible for most of the total impact on most systems except for solar heater. The main conclusion is that, in Brazil, water-heating systems that use electricity and solar energy should be preferred over those that use natural gas.

Coal pyrolysis and carbonization device of coal pyrolysis furnace

Abstract: The utility model discloses a coal pyrolysis and carbonization device of a coal pyrolysis furnace. The coal pyrolysis and carbonization device is arranged in the middle of a furnace body and mainly comprises a carbonization chamber, an external gas heating device, an inner combustion heating device and a flame path arch, wherein the carbonization chamber is positioned above the flame path arch and a ring-shaped space is formed through the inner and outer ring walls made of a fireproof heat-conducting material; the external gas heating device is positioned around the ring periphery of the outer wall of the carbonization chamber, the external gas heating device mainly comprises more than one group of first gas heater and second gas heater and a gas reversing device, and the first gas heater and the second gas heater are the same in structure; the inner combustion heating device is positioned inside the ring of the inner ring wall of the carbonization chamber, the inner combustion heating device mainly comprises a group of third gas heater and fourth gas-burned heater and a coke-quenching waste gas heater, and the third gas-burned heater and the fourth gas-burned heater are the same in structure. The coal pyrolysis and carbonization device disclosed by the utility model is mainly characterized by providing sufficient temperature and heat for coal pyrolysis and carbonization through the comprehensive utilization of a gas generated in a coal pyrolysis and dry quenching process without additionally providing an extra heating energy-consuming device, thereby reducing the coking cost. The coal pyrolysis and carbonization device of the coal pyrolysis furnace is environment-friendly and economical.

Ability of swimming gas heater is mixed to rear end

Abstract: The utility model provides an ability of swimming gas heater is mixed to rear end, the inlet tube is equipped with water flow sensor, advance the water inlet of water piping connection heat exchanger,the delivery port of heat exchanger is connected to the water inlet of hot water inlet tube, the outlet pipe is provided with out water temperature sensor, direct pipe and bypass equipment's water inlet is connected to the delivery port of hot water inlet tube, the water inlet of outlet pipe is connected to direct pipe and bypass equipment's delivery port, direct temperature sensor sets up in hotwater inlet tube or direct pipe, bypass equipment is equipped with the water server, water flow sensor, direct temperature sensor, an outgoing water temperature sensor, the water server all is connected with the controller, the gas heater leaving water temperature is unstable in solving prior art, and the comfort level is relatively poor and the security is lower defect realizes that the gas heater leaving water temperature is invariable, proposes high comfort and security.

Freeze -proof device and gas heater that prevents frostbite

Abstract: An embodiment of the utility model provides a freeze -proof device and gas heater that prevents frostbite relates to gas heater technical field. Freeze -proof device includes main control unit, temperature controller, generate heat device and power module, and temperature controller, generate heat device and power module all are connected with the main control unit electricity, and power module includes battery and outer power source, main control unit still electricity is connected with drainage unit, and drainage unit includes three -way valve, drain pipe and stop valve, and the stop valve sets up in the drain pipe, drain pipe and three - way valve connection. It is through detection ring border temperature and power supply mode, the automatic selection mode of preventing frostbite, moreintelligent, after the time of the device heating of generating heat reached the time of predetermineeing, the main control unit control drainage unit carried out the drainage and prevents frostbite,can practice thrift the consumption of electric energy and the life who prolongs the device that generates heat, and is more energy -conserving, when taking place proruption power failure accident, the battery is supplied power for main control unit and is kept main control unit's work, can not influence the frostproofing protection to the pipeline, and is safer.
