Method for safe operation of oil or steam boilers steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. 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. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Steam boiler furnaces operating point of the device first starts the circulation pump, the circulation pump outlet pressure, the furnace, the furnace pressure, and the system should ensure the return pressure in the normal range. Circulation pump run for 30 minutes before entering the next step, the system is stable. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, once the accident shut down the phenomenon occurs, the device automatically interlock the burner will be protected, should be promptly cut off the natural gas pipeline, furnace cleaning function should be started. Replace the rest of the gas stove, and stop cleaning. The system load requirements, temperature requirements and thermal oil outlet, the burner can automatically adjust the size of the fire source.
Small gas oil or steam boiler gas boiler works as the name implies refers to the fuel gas boilers, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas-fired boiler steam boiler facilities, heating, bath with . Gas boiler comprising KS-Q water gas boiler, CLHS (CWNS) gas hot water boiler, LHS (WNS) gas steam boiler and the like, wherein the gas comprises a gas hot water boiler heating boilers and gas boilers bath, with the state "natural gas "project implementation, gas boiler gradually become the people's choice. Evaporation general industrial boilers are relatively small, all below 40, to about 10-35, mostly, but also the use of industrial boilers and boiler power plant are not the same, the main industrial production boiler steam and hot water requirements index is not very high, Some general-purpose industrial steam is used, for example, a lot of steam seal the furnace, hot water steam heating and other uses, in the form of industrial boilers, furnaces most mostly a chain, because chain boiler technology is mature, simple and reliable construction, also automated, etc. factors, by the majority of users of all ages boiler. Chain has chain structure of the furnace grate, coal gate, eagle iron, the furnace, the slag discharge pipe, water wall, the upper and lower header, superheater (steam boiler there), the convection tubes, upper and lower collection tank (also known as drum), province coal filter, air preheater, and corresponding systems and auxiliary pumps and fans, as well as instruments and other devices. The structure is characterized before and after the formation of more water wall furnace arch, it is to promote ignition and combustion, the combustion more complete. Grate bin wind, the wind can be equipped according to the amount of coal burned specific distribution of silos. There are pulverized coal power plant boiler circulating fluidized bed boiler and the main in an amount greater evaporation gas boilers, high efficiency, structure and chain furnace different, similar to the structure of pulverized coal and circulating fluidized bed boiler, but different principles, coal powder and circulating fluidized bed boiler furnace are used with a bed of air holes, the primary air into the drum by the bed, secondary air into the furnace to carry the pulverized coal combustion mixture is formed, separated by the cyclone after burn unburned complete coal combustion again, fluidized bed boiler pulverized coal stream is formed form, better than pulverized coal fired combustion, combustion, low temperature combustion is also achieved, reducing the emission of nitrogen oxides. Fuel oil-fired boiler is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, methane, etc.), depending on what fuel boiler combustion devices called burner, gas burner configuration called boiler gas-fired boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners.
Three tempering tube hot water boiler installation and commissioning of the structure outlined hot water boiler is fast loading of the internal combustion level. A second high temperature flue gas successively washed roots and refluxed for three breathing tube, the smoke chamber into the atmosphere through the chimney. Gas hot water boiler equipped with the world famous burner, combustion using automatic adjustment, automatically adjust the water supply, the program starts, automatic control and other functions. The boiler has a compact, safe, reliable, easy to operate, installation speed, low pollution, low noise, high efficiency. Widely used in enterprises, hotels, hospitals, office buildings, civil construction and other industrial steam, life, mining and other facilities. This installation requires fast speed boiler installation, installation is very simple, the boiler does not require special ground base, only enough to withstand the ground to power. 1. Install the water supply line requires the highest level reservoir, generally not critical, the high from the ground to the reservoir tank, underground tank of water should be kept clean. Pool water outlet. For wire entrance filter water supply line. 2, the straight cross-section is mounted, the return pipe return pipe to be 0.5 meters above the bend radius should be 4 to 5 times the diameter of the pipe, the pipe should be installed at the highest automatic steam valve to prevent the steam from the pipe loop. At the same time, the general requirements of the highest level possible reliable reserve pool. When the boiler water level is below the line, the water will flow into the boiler when the next time you start. Filter wire 3 should be installed at the outlet (i.e., the inlet pipe) of the pool. Installation requires a supply line Burner fuel hose has two interfaces, and for the oil return into the oil, as long as the boiler return oil chamber and the oil corresponding feed pipe. Dedicated hydraulic system from the boiler tank to the burner pump port, an operation instruction for the burner 4 is provided. Chimney straight chimney installation requirements. The length of the chimney should not be too long, the stack height should be less than 5 meters. Chimney height should comply with relevant standards. Chimneys should be added raincap and smoke. Weight not directly on the boiler chimney host chimney 5, hydrostatic test shall be carried out after the installation of boiler water pressure test supervisor. Pressure test before proceeding to deal with internal boiler inspection, hydrostatic test pressure MPa, during hydrostatic testing, water pressure should slow down. When the pressure rises to 0.1MPa, the water pressure should be increased to 0.1MPa. When the ambient temperature is higher than 5C, hydrostatic test should be carried out; when the temperature is lower than 5, should be protected from freezing water pressure test. Hydrostatic test water is generally 20-70.6, should be as light fuel oil or gas oil (China) as the fuel, the fuel oil is generally heated to 100 deg.] C, a viscosity less 30E. Oil Qbw = 10200Kcal / kg LHV viscosity of the oil is lower than at 50 ℃ 200E, at less than about 80 ℃ 200E, 50e is less than the heat value of natural gas Qbw = 8550Kcal / kg LPG Qbw = 22000Kcal / kg.
