Embodiment
A kind of boat low-temperature fuel gas supply system heating arrangement as shown in Figure 1, comprise the heating circuit be made up of jacket water heater, steam heater, combustion heater, recycle pump, heat medium supply cabin and the pipeline that connects above-mentioned each structure, in described heating circuit, be provided with heat medium; Described jacket water heater is connected to main engine jacket water inlet and main engine jacket water out, and described main engine jacket water inlet is connected with main engine jacket water cooling system respectively with main engine jacket water out; Described steam heater is connected to steam inlet and steam (vapor) outlet, and described steam inlet is connected with steam supply system, and described steam (vapor) outlet is connected with condensate water processing system; Described combustion heater is connected to fuel gas inlet and gas outlet, and described fuel gas inlet is connected with gas-fired equipment respectively with gas outlet, and in described heating circuit, jacket water heater outlet and steam heater outlet are also provided with thermostat valve and temperature transducer.
As the optimized project of above-described embodiment, the steam heater of this structure is standby equipment, when jacket water heater heating after temperature can not meet low temperature gas burning system temperature required time, steam heater can be started and heat.The jacket water temperature of jacket water import is 80-95 DEG C, the gas outlet temperature of combustion heater is 35-55 DEG C, the temperature value that jacket water heater outlet temperature sensor detects and gas-fired equipment need temperature value to contrast, thus control the heating medium flow through jacket water heater; The temperature value that described steam heater outlet temperature sensor detects and gas-fired equipment need temperature value to contrast, thus judge whether steam heater works and through the heating medium flow of steam heater.Heat medium is ethylene glycol water, and wherein ethylene glycol accounts for 60%, and water accounts for 40%.
The heating means of said structure realize required heater and comprise jacket water heater, steam heater and combustion heater, and heating procedure comprises following several step:
(1) jacket water is utilized to heat jacket water heater;
(2) jacket water heater heats heat medium;
(3) heat medium heats combustion heater;
(4) combustion heater heats low temperature combustion gas;
(5) steam heater is back-up heater, service condition for the shortage of heat when cylinder jacket heating device with the condition meeting low temperature gas heating institute calorific requirement under use.
The system control method of this structure realizes by the flow control of the control to the heating medium flow through jacket water heater, the heat medium through steam heater, heating medium temperature monitoring the heating that utilizes jacket water to boat low-temperature fuel gas supply system:
