Gas chemical industry pressure water tube boiler room location should pay attention to these issues need to pay attention to the location of gas boiler room boiler room of a problem than how specific to the site, more customers just curious boiler room and other buildings safe distance, do have customers believe boiler room just fills the room, as long as the boiler plant went on line, do not need to sun and rain. But in fact, the boiler room location is very important, it is related to a series of questions of your initial investment and system planning, job handling and safety protection. With gas boiler, for example, for us to introduce issues related to pay attention to the orientation of the boiler room. 1, the orientation of the gas boiler room should be summarized gas type, boiler capacity, operating pressure, supply and return water temperature, the system in the form of building types and other factors to consider. 2, natural gas boiler room planning should be "boiler room planning norms" (GB50041-2008), "town gas planning norms" (GB50028-2006), "building plans for fire protection" (GB50016-2006), "the senior civilian in accordance with existing national norms architectural plans for fire protection "(GB50045-95) (2005), and" hot water boiler safety skills supervision "(labor pan word [1997] No. 7) are summarized concluded. If there are local with local codes, with the satisfaction to consider. 3, gas boiler room should be set in separate buildings on the ground, if the conditions are bound, connected to the main building or need to set up in the basement of the main building, semi-basement, while the first floor, the top floor and center floor, shall be approved by the local fire, safety supervision and environmental protection part of the agreement. 4, gas boiler room directly prohibit people gathered in the room (such as public baths, classrooms, auditoriums, shops, restaurants, waiting rooms, etc.) or at the top, bottom, or top lax immediate neighborhood of the mouth on both sides. 5, the new residence should not be connected to the boiler room, boiler room and other adjacent buildings, the wall adjacent to the firewall. Boiler room on the ground should be flat without steps, and should prevent accumulation of water. 6, because the conditions there are shackles, located in the basement boiler need, center or top floor high-rise buildings or multi-layer, prior consent of the city, prefecture-level and above safety watchdog agree. In addition to the above requirements satisfaction, it should also be satisfied: (1) each boiler rated evaporation does not exceed 4t / h, the vapor pressure does not exceed the rated 1.6MPa. (2) oil is necessary, as a fuel gas or electric heating boiler. (3) the fuel supply line adapter using welding backing. 7, as provided in the boiler room in the basement or the first half-layer or multi-layer high-rise buildings, it is necessary to fit together the following conditions: (1) each boiler rated evaporation does not exceed 10t / h, the vapor pressure does not exceed the rated 1.6MPa. (2) Each boiler necessary to have reliable overpressure protection device interlock and interlock the bottom level protection. (3) accessories and safety interlock protection device for each boiler to regular maintenance and experiments to ensure active, reliable. (4) the building structure between the boiler should be the appropriate seismic measures. (5) operating independently fireman fireman operating permits necessary to hold the appropriate level of boiler and continuous operation of the same class more than five years, has not had trouble occurs. (6) the need to have lax security channel.

Temperature protection device during the fuel steam chemical industry pressure water tube boiler overtemperature protection to regulate temperature protection is an important part of safe operation of steam boiler fuel, especially fuel steam boiler temperature regulation and protection. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Meanwhile, when the superheated steam boiler fuel, can play a role in the regulation and protection. Conventional boiler temperature protection means is a bimetallic temperature controller. Flame protection: To prevent the furnace blast, the fuel steam boiler must be equipped with flame protection device, and its function is combustion within the monitor cavity (including ignition misfire on or off in the middle of the combustion, is generally re-ignition within 5 seconds, within 1 sec. running off the oil (gas) solenoid valve, and opens the concurrent silent alarm signal, when the blower continues to operate, remove residual combustible gases in the furnace, after 20 or 30 seconds purge, and various auxiliary blowers automatically cut off power boiler stop running. flame monitor function signals displaying a flame presence or interrupt from the control device. its main use is a photomultiplier tube, photoresistors and photocells, they have an ultraviolet or infrared type photoelectric conversion element, its operating the principle of light radiation intensity is converted to the corresponding high current and low current and the output is a linear state, the induced current is sometimes weak, and thus affect the controller amplification.

Recently, the Guangzhou City issued an action "Guangzhou 2018 annual work plan for comprehensive prevention and control of air pollution," the bureau of law enforcement to monitor the detachment on August 28 = 29 organizations launched a special enforcement action against a biomass chemical industry pressure water tube boiler.

Gas-fired steam chemical industry pressure water tube boiler 5 important protection mechanism, you have mastered it gas steam boiler is the main driver of industrial production and daily life provide hot water for enterprises, to buy long life, high efficiency heat transfer, high cost of gas steam boilers, is very important. To ensure the long life, from the boiler manufacturing, installation, operation and post-conservation measures start. Today, we talk about focus, gas steam boiler 5 important protection mechanism is to protect your boiler plant by what really works. 1, when the high temperature protection dry protection when the furnace temperature is detected to exceed 95 ℃, immediately cut off the heating power supply pipe, to prevent further increase in temperature. 2, when the system detects leakage protection when the leakage current exceeds 15mA, will immediately cut off power to prevent electric shock to human exposure; while the display prompts and warnings fault code, troubleshooting, restart the controller can continue to work normally. 3, when the antifreeze function in case of power control, start antifreeze function when the detected temperature is lower than 3 ℃, start heating heater; when the detected temperature is increased to 8 ℃, the heater stops heating. 4, set the boiler on various parameters of recording and saving functions are automatically recorded and saved, even if it is cut off the power supply does not need to re-set. When the time is set gas steam boiler is completed, the power-down can also be run as usual, do not correct the time after power again. 5, the temperature control function is not set if the operating temperature of the power, the system will work in accordance with a default parameter setting 50 ℃; if the set temperature, the set temperature of the press run. When turned on, the controller detects that the heating temperature is lower than the set temperature 8 ℃, by setting the gear, turn the heating tube, the heating temperature when the detected temperature is equal to higher than the set power off, stop heating. The temperature was slowly lowered to open again below the set temperature 8 ℃ heating tube, and so on, to achieve the purpose of temperature control.
