Gas boiler safe operating procedures: gas-fired boilers this kitchen I believe we are not unfamiliar fishes it. But this thing is not so easy, and sometimes improper operation causing very serious consequences, so the gas boiler rules is very important. That in the end this is how the specific operation of it, if you want to know, quickly told us with a look. 1. All personnel must be familiar with the operation of the boiler performance and safety knowledge of the boiler operating certificates. This post is strictly prohibited non-operating personnel. Duty should be strictly in accordance with the operating records and do a good job shift recording, the security situation and the device should shift change operation tests, carried out. When the shift to check the boiler is intact. 2. Boilers and safety accessories should be inspected, and in the period. 3. Kai blast furnace gas furnace ready ① Check if the gas pressure is normal, not too high or too low, open the door of oil and gas supply section; ② Check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Open the Water Supply System for each section of the door (front door section Sheung including pumps and boilers); ③ check level gauge, the water level should be in the normal position, the water level gauge, a water level required color plug in the open position, the water level to prevent false, if water can be manually Sheung; ④ check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob ⑤ checks the control cabinet are in their normal position; ⑥ siemens plc control oil fired steam boiler check valve should be in the closed state hot water boiler circulating pump outlet valve should be turned off; ⑦ checking water softening equipment is operating properly, a variety of indicators to create a soft water meets national standards. Open the power ⑴; ⑵ startup burner; ⑶ purge valve on the drum, is completely out of steam, the off; ⑷ inspection hole into the boiler, and the hand hole flange valves, the leak was found to be fastened, tight as the solid leakage maintenance shutdown; ⑸ pressure rise when 0.05 ~ 0.1MPA, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; ⑹ when the pressure was raised to 0.1 ~ 0.15MPA, flushing pressure gauge trap; ⑺ when the pressure was raised to 0.3MPA, "fire load / small fire" knob to "fire" to strengthen the combustion; ⑻ when the pressure was raised to 2/3 of the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; ⑼ drain valve is completely closed out of steam; ⑽ after all the drain valve closed, slowly open the main valve to open, and then half a turn; ⑾ "burner control" knob to " Auto "; ⑿ level adjustment: adjusting the water level (to manually start and stop the pump) according to a load, low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; ⒀ steam pressure adjustment: adjusted according to a load combustion (manual adjustment Fire / small fire) ⒁ combustion state determination, determines the amount of fuel atomization air ⒂ observation condition exhaust gas temperature, smoke, temperature control is generally between 220--250 ℃ The flame color, smoke color, while observing the chimney exhaust gas temperature , concentration, adjusted to the optimum combustion state. ⑴ Open the power; ⑵ start the circulation pump; ⑶ slow circulation pump outlet valve; ⑷ startup burner; ⑸15 min "" Load fire / small fire "bit color button is turned to" fire "" ⑹ "burner control" knob spin to "automatic." 5A normal shutdown: hot water boiler ① "fire load / small fire" knob to "small fire"; ② off the burner; ③ close the fuel supply valve; ④ ⑤ closing dampers boiler after the temperature dropped to 50 ℃ , the circulation pump outlet valve closed. ⑥ stop circulation pump
Gas siemens plc control oil fired steam boiler not only focus on their own function and more environmentally friendly gas-steam oven due to heat and heat transfer equipment, and for many professions. Screening of its upgrade and shopping centers is very high, and even some of the new products will be screened in a few years. If we can not meet these requirements, this highly competitive industry on the development of the oil furnace put forward new requirements. If you do, you will certainly face a screening room. Today's gas-steam oven not only focus on their own function, but also more environmentally friendly. As long as the bow is in line with today's society about the development of high-tech products, otherwise it will be empty talk. Insulation gas steam oven is a very important factor to measure the value of its shopping centers. Steam oven gas having good insulation function expensive than about 20% of oil furnace insulation function difference. Do not underestimate the 20% of the costs and profits. A very scary figure. Gas insulated steam oven is mainly reflected in its interior. Some oil furnace with a heat insulation material, which is integrated with the oil furnace. They do not conflict with other raw materials. Let's talk about this oil furnace. The product is called high-tech insulation oil furnace products. Because it is equipped with a high-quality insulation material, and therefore require a longer heating temperature and longer data to assist the burning material processing company. The purpose is to save money for the company. At present, commonly used as a furnace gas and steam insulation materials include products of rock wool insulation panels, foam insulation board cement, Portland composite panels and aluminum panels. We expect a wide range of gas-steam oven manufacturers will focus on the selection of the insulating material. Them into account, because they are really suitable for insulating oil furnace.

PRODUCT INTRODUCTION fuel gas-fired boiler fuel gas-fired boilers and coal-fired siemens plc control oil fired steam boiler is not the same, gasoline and diesel and gas-fired burner must be poured into the fuel to the boiler furnace using a combustion chamber rather than grate facilities. Since the fuel gas-fired boiler is not easy to cause the fly ash lit, so no oil or gas boiler slag removal equipment. If mixed with air or exterminate within a certain range, it is introduced into the furnace petrochemical and gas easily the explosive. Thus, any gasoline and diesel and gas-fired boilers must be selected and automatic combustion control system. Compact boiler fuel gas, and the small boiler exhaust, drainage, control and auxiliary equipment installed at the distribution panel, and produce large and small boiler assembly. Fuel gas-fired boiler safety valve installation key point describes the installation of fuel gas-fired boiler safety valve sure to carry out in accordance with reasonable installation process, to prevent wrong and lead to risk. Fuel gas-fired boiler safety valve installation should pay attention to what matters? The following is a brief description: 1 oil-fired boiler safety valve having a lever bar to avoid self-weight and the mobile device guide body defining deviant lever, the spring valve lift handle and avoid the need for screw adjustment means random twist. 2. Rated evaporation than 0.5t / h gas boiler safety valve should be arranged at least 2, Rated evaporation gas boiler should be equal to or less than 0.5t / h, fitted with at least one safety valve. Separable economizer outlet and a steam superheater outlet valve should be installed. Sectional area of the connecting pipe between the boiler safety valve 3. Fuel gas boiler can not be lower than the imported cross-sectional area of the valve. If several valve mounted on each stub is directly coupled to the drum, the passage sectional area of the stub is less than 1.25 times not all of the area of the exhaust valve. 4. Oil and gas boiler safety valve should be mounted vertically in the height of the boiler drum and the header. Can not be mounted between the valve and the steam outlet conduit and the valve drum or header. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25 mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20 mm. 6. Fuel gas boiler safety valve should normally be established an exhaust pipe, the exhaust pipe should be directly connected security grounds, and there is sufficient cross sectional area to ensure the smooth flow of the exhaust gas. The bottom of the valve should be equipped with an exhaust pipe connected to the drain of a safe place. Valve must not be installed in the exhaust pipe or drain pipe.
