Gas hot water boilers of chemical equipment, there is a certain risk running, so to develop a number of operating standards, to regulate and protect the safe operation, its operational standards are as follows: 1. Each hot water boiler safety devices must ensure reliable, Safety features include flame protection, gas overpressure protection, overtemperature protection and water furnace ultra protection. 2. According to the special requirements of gas hot water boilers, each boiler must be using the automatic ignition process. Boiler installation of each system should ensure reliable and accurate pressure gauge and check them regularly. 3. Depending on the conditions, the operation of water pressure to ensure that ¨ò 0.10Mpa, the water pressure to ensure that ¨ò 0.08Mpa, and to ensure there is enough water pressure. The gas hot water boiler water temperature required: the boiler outlet temperature does not exceed 85 degrees Celsius; the heating season should the water temperature according to the ambient temperature regulation system, the system water temperature set / trap temperatures prevail, steady heat, the night temperature does not less than 50 degrees, the water temperature during the day reached 55-60 ° C; daytime running balance tank heating temperature is not lower than 60 degrees Celsius, at a temperature of not lower than 55 degrees Celsius, the night temperature is not lower than the balance tank 55 degrees Celsius, at a temperature not lower at 50 degrees Celsius. According to the ambient temperature at any time to adjust the operating temperature. 5. The hot water boiler water requirements are: operation of boiler water pressure of not less than 0.8bar; system to timely pay, the minimum pressure is not lower than 0.08Mpa; normal sewage, deflated, to ensure the normal equipment and systems reliability. 6. The gas inlet pressure should ensure 100Kpa to 110Kpa, whereby pressure to clean inlet filter and tuning 7. Gas pressure hot water boiler room should be regularly ventilation, and to ensure clean environment and equipment. Using the most sophisticated three return all wet back structure, safe and reliable; using corrugated furnace and threaded pipe, increasing the heat transfer effect, improving the thermal efficiency; unique large combustion chamber design, increasing the radiation heating furnace area, narrow the volume of the boiler, reducing Nox emissions; multistage seal around the smoke chamber, to ensure that no dew smoke; adopts PLC control, multi-chain protection. Large steam space, good steam quality; adopt effective thermal insulation materials, boiler outer surface temperature is low, the heat loss is negligible; in strict accordance with Chinese national norms and standards, all of boiler pressure parts are made of high quality steel; every boilers undergo a rigorous inspection and testing, including pressure testing and X-ray inspection. Specifications of boiler capacity boilers to produce steam or to heat water and levels. Steam boiler specification unit time to generate steam and steam parameter indicates the number of hot water boiler specification unit time to the heat and hot water for the parameter represents. Number of steam boilers produce steam per hour called evaporation of the boiler, also called capacity or output of the boiler, usually the symbol "D", said unit t / h (t / h). Evaporation of the boiler on the nameplate typically rated evaporation, ie steam boiler at a predetermined parameters and water temperature, continuous operation must guarantee maximum evaporation. Hot water boiler capacity per unit time is water in the boiler's heat absorption unit as MW (megawatts), which referred to the rated thermal power rating or rated for heat. How much media heat boiler and steam production is directly related to the number of boiler heating surface. Boiler heating surface is separated from the flue gas and water vapor, and the heat from the former passed to the latter's metal wall, usually cylindrical wall tube or steam parameters of steam boilers in the boiler main steam valve at the outlet of the steam pressure (gauge pressure ) and temperature represent. Medium parameters hot water boiler with rated water pressure (gauge pressure) and rated outlet / inlet temperature represents. Pressure and temperature, respectively, the symbol "p", "t" represents. 1) gas boiler and burner control system jointly completed a number of programmable devices reliable control and protection functions; 2) boiler temperature display, temperature control, over-temperature alarm and other security systems set up independently. Gas boiler water temperature control and overtemperature protection are three different sensor completion signal transmitted by the complete 3) boiler temperature control and protection of three different control units: Boiler Control System provides multiple temperature protection: A, temperature setting knob to control the temperature. B, boilers boiler water temperature regulator to limit the protection (water temperature reaches the set value of the automatic shutdown). C, boiler controller operating unit electronic temperature limit protection. D, boiler controller Boiler overtemperature protection (water temperature reached 110 degrees automatic shutdown hand manual reset); 4) burner flame failure protection, burner fault turn off automatic fuel shut off valve and alarm; 5) pressure protection: air pressure is too low, the burner does not start, ensure matching with the combustion pressure and operational safety; 7) boiler overpressure protection: by gas boilers at the outlet of the pressure limiter achieve shutdown boiler overpressure protection and alarm signal output ; 8) Gas pressure protection: when the gas pressure is less than the minimum gas pressure switch setpoint and above the maximum gas pressure switch set value, the burner can not start, can be another shock to the normally closed communicating alarm;
