In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving 1510 kg steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
Laundry hotel special reference to the current selection of 1510 kg steam boilers Hotels generally use the hot water boiler for heating and sanitary hot water, kitchen utensils gas can be directly used, but still need to supply steam laundry room, laundry room steam supply pressure to be 0.4-0.6 MPa, generally an amount of steam in the hotel laundry 0.5 ~ 2.0T / H, steam day with about 3 to 10 tons. Under the premise of the city's coal-fired boilers can not be used, the choice of energy sources natural gas, diesel, liquefied petroleum gas, electricity, in what exactly it is more appropriate? First use to compare the cost of various energy sources, according to Henan hotel energy prices, natural gas is 3.0 yuan / Nm3, diesel 9.0 yuan / kg, liquefied petroleum gas 15 yuan / Nm3, the price of 1 yuan / kwh. Compare 1 ton of steam produced by a variety of energy costs as follows: Energy Category Energy calorific value of natural gas in energy costs per ton of steam 8600kcal / Nm380m33.0 yuan / Nm3240 yuan / ton diesel 10400kcal / kg66kg9 energy consumption per ton of steam energy prices. 0 yuan / kg594 yuan / ton liquefied 22000kcal / Nm331m315 yuan / Nm3465 yuan / ton electric 1kwh700kwh1 yuan / kwh700 yuan / ton Note: energy consumption efficiency estimated by conventional steam boiler; Nm3 refers to the standard state volume of gas M3; calculated from the above analysis, the use of natural gas per ton of steam lowest cost, most economical operation, electrically heated steam up costs. Gas steam boiler typically 2 to 3 sets of selection, single nominal amount of evaporation 0.5T / H ~ 1.5T / H. Gas-fired steam boiler boiler range belong to the state regulators, the need to build a separate boiler room, not like pressure hot water boiler as the main building or in the basement, while the city hotels are often difficult to have a location to build a separate boiler room. In recent years, there is a new type of gas steam boiler, the water capacity is small (less than 30L), a single evaporation accessible 1T / H, do not belong to the state boiler steam boiler regulation range, can be in the basement, a good solution to the conventional steam boiler no suitable location problems.
Gas-fired 1510 kg steam boiler FAQ boiler for your boiler sorted out 30 common problems and solutions, do not forget to share a small partner after learning finished oh. 6, the main factors which influence the rate of wear of? ① flue gas, the concentration of the surface shape of the particle size and hardness ② ③ material in the flue gas flow rate of the material is worn element, the direction of relative movement of material with the hardness of the wear element ④ greatest influence It is the speed of the airflow, proportional to the cube of wear and speed. 7, how to control the bed temperature between 850-950? ① ash does not melt at the temperature, thereby reducing the risk of slag settle ② The temperature nitrogen having a high desulfurization efficiency ③ combustion gases at this temperature ④ less of the gas at this temperature the coal is not an alkali metal sublimation can be reduced slagging of the heating surface. 8, why should the torch boiler? Soda boiler system equipment such as part of desuperheating water, startup bypass, superheater, reheater piping system, due to the structure, material, arrangement, etc. are not suitable for chemical cleaning, so newly installed inside the boiler required physically remove remaining debris before officially put into operation, it is produced using the steam oven of the present systems and devices torch soda process. 9, common maintenance method, which has several boiler (1) Wet protection: with ammonia, liquid ammonia method, a method to maintain water pressure, steam heating method, a method of alkali, trisodium phosphate, and a mixed solution of nitrite Protection Act;? (2) dry protection: drying method (with pressure drainage) and desiccant process. 10, what? (1) steam with water vapor causes of quality deterioration (steam pollution). Boiler feed water containing impurities. After heating into the boiler feedwater into steam, most of the impurities are also transferred to the boiler water, so many times the cycle, increasing the impurity concentration of boiler water. Boiler water containing a high concentration of impurities is carried with the steam is called saturated steam water vapor with a machine called water carried, the first reason is contaminated steam. (2) steam soluble salt. The boiler at a higher operating pressure steam dissolves some salts, referred to as selective carry steam soluble salt, which is the second reason steam contamination.
In order to ensure boiler safety, to run smoothly, you must ensure that the use of high-quality natural gas. 1, equipped with one gas separator to increase the capacity, it can effectively store oil and water. Secondly, a level gauge designed to directly observe whether there is liquid in the separator. While the design of the automatic drain pressure relief device is installed. A single control pressure of the air is improved dual control, i.e. the pressure regulating valve is mounted on the main line to control the water separator, the pressure to stabilize, improve security purposes. 2, safety monitoring natural gas as a boiler room burning materials, natural gas leak monitoring must be done. The portable display technology poor performance, poor sensitivity. Host combustible gas alarm system with digital control scaling circuit having an alarm function and a secondary alarm, ensure the safe operation of the boiler. 3, check before firing the safe operation of: (1) whether the boiler inspection gates normally open or closed, check the gas pressure is normal, not too high or too low, open the supply valve leading to the boiler. (2) in the flue baffle must be fully open, otherwise it will affect the purge, causing accidents. Each knob and keep control cabinet to check the normal position. If the stove has a residue should be cleaned. (5) Check the boiler ignition and fire protection program control means should be flexible and reliable. Blast doors should be flexible and rigorous on the boiler. Before the completion of ignition, the ignition is not possible to start the ignition operation: After successful ignition, the load can be adjusted in the normal operation of the boiler when the combustion gas boiler adjusted. We should always observe the combustion furnace, and adjust the amount of steam, wind and steam pressure to ensure the safe operation of the boiler. Note: Program: first five minutes were furnace cleaning, automatic ignition after 5 minutes, observe the ignition is successful, the success of one minute after a small fire can be operated automatically converted to fire properly. For the boiler load and the air pressure adjusted by adjusting the pressure regulator to achieve. When adjusting the load, adjust the air pressure at the same time, it must be synchronized to adjust the air flow to ensure a reasonable match air volume and air volume, in order to achieve economic operation of the boiler. In normal operation, the amount of gas should not be adjusted or reduced drastically in order to avoid dramatic changes in combustion, the pressure receiving member sudden expansion, shrinkage and damage. When the boiler is running, the pressure gauge must be monitored regularly in order to maintain stable water pressure. BCP pressure changes observed, reflecting the relationship between water temperature and steam consumption. In the boiler operation, when the steam pressure is automatically adjusted, the main purpose of the staff is to monitor automatically adjusts the boiler system is sensitive and timely solutions to problems and ensure the sensitivity and reliability of the automatic control system. 4, first close the main valve shutdown operation, the air supply is stopped, the circulating pump and the water pump is still running, when the boiler water temperature falls below 70, and supplies or stops the circulation pump in operation of the pump after about 4 hours. Note: In addition to the accident and emergency parking stop, parking general approach should not cut off the power. After the shutdown, it is timely for the boiler and ancillary equipment to conduct a comprehensive inspection. If you find a defect in the device, and repair should be recorded at the time of shutdown. Safety Precautions 1. burner startup, if the burner is repeatedly locking and alarm, you should find out the cause of the malfunction, press the reset button after troubleshooting, press the reset button and then continue to boot. Note: Press the Reset button for less than 10 seconds. A lower burner inlet must be clean and clean, and does not allow offal. 2. burner once the ignition is unsuccessful, Boiler Fan should be restarted. Ventilation After 5 minutes, start the second startup burner igniter. three. During normal operation, the thermal device near the burner portion (e.g. flange connections) will be very hot, in order to avoid burns. Do not put flammable materials in the vicinity so as not to cause a fire. 4. The operation of the boiler circulating pump must be closely monitored and the hot water boiler pressure, gas distributor, pipeline valves, pressure gauges, flow meters, water level gauge and the like. 5. When the firefighters open the door or fire door observation, you should wear gloves and a side view. 6. A burner working environment should be kept clean and dry, in particular, a flame detector (i.e. electric eye) should be kept clean, part of the control circuit should humidity and temperature; class should cleaning and maintenance of a combustor. 7. During use, the filter should be cleaned regularly check or replace the filter cartridge in accordance with impurities of the fuel. 8. Check the electrical installations include: wire is damaged, the sheath is damaged, the screw is loose, the contact is good, whether the motor is running abnormal noise. Describes the advantages and disadvantages of natural gas boiler, editor of Sin sets introduced, the use of technology and safety precautions. Industrial boilers to energy efficient, environmentally friendly development direction. Natural gas boiler to meet the needs of these three points. They are the future of the boiler market trend, more and more restricted energy policy, energy saving and environmental protection requirements.
