Check the work before the start fuel gas-fired boiler in order to protect the safe operation of the gas boiler, improve operational efficiency boiler, make sure to check the work before the boiler starts, every detail can not be ignored. 1, check the safety accessories, thermal instrumentation, electrical instrument should be intact; 2, check the connections, whether the water leakage and the furnace body line; 3, check the waste line, the water line, return line should be smooth; 4 , should check the line voltage is 380V, the fluctuation should be within ± 5%; 5, oil-fired boiler and a filter pump check whether normal oil, gas boiler check the gas pressure is normal, not too high or too low, the oil supply opening valves; 6, check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Water Supply System opens each valve (including the water pump and water valve before and after the boiler); 7, check level gauge, the water level should be in the normal position, to prevent false water level, if the water can be manually Sheung; 8, check the pressure conduit the valve must be opened, the wind deflector must all flue opening; 9, each knob inspection control cabinet are in their normal position; 10, a check valve should be steam boiler in a closed state, the hot water boiler in vietnam circulating pump valves should be closed state; 11, check water softening equipment is operating correctly, create a variety of indicators of soft water meets national standards. Carefully do the above inspection, the basic conditions for the fuel gas boiler safe and economic operation.
Safety precautions when using electric boilers hot water boiler in vietnams has many safety precautions, especially hot water boilers, it is more to pay attention to some of the security detail during use. In operation hot water boiler must be put in line with the provisions of clothes, carefully check all parts of the boiler system, such as pressure gauge, safety valve, gas pipe fittings, water level, etc., everything is correct before continuing work. Must pay attention not to water one-handed operation, one hand and water in one hand and the door is open water steam valve, when the water column to a predetermined level, the first valving then off Watergate, this order can not be reversed, and the valving face when not to It is on the water, to prevent splash injuries face. In the boiler has been at work, surrounding someone must guard the moment the water level and pressure gauges, there can be no neglect of duty, if the night shift work, be sure to have a good rest during the day, so that when the work will not fall asleep at night, because once any carelessness, accidents will happen. And every night the boiler sewage treatment, water table should clean up once every night. For motor and other mechanical equipment have always been its inspection, if any abnormal findings, the investigation must be immediate. Weekly safety valve should be checked whether it is safe.
Operating cost comparison of different fuel steam boiler below Henan fast boiler with small series to introduce the company's operating cost comparison of different fuel steam boiler. Refers to a steam boiler water heated to a certain temperature parameters, and the production of industrial steam boiler, water is heated into steam in the steam drum, the fire in the furnace emits heat, it is the principle of the steam boiler. Steam boiler belongs to special equipment. Gas: Advantages: clean energy, high thermal efficiency and save costs. Disadvantages: Restricted gas on condition. Generating a cost of about 2.4 tons of steam million (calculated as the price of 3.2 yuan gas / side) fuel: steam boiler advantages: no pollution, high efficiency, no fuel limitation. Disadvantages: higher operating costs. Produce one ton of steam costs about 594 yuan (fuel prices by 9.5 yuan / kg calculated) electrical heating: advantages: no pollution, no fuel limitation. Disadvantages: is a secondary energy, high operating costs to produce one ton of steam costs about 700 yuan (electricity prices by 0.6 yuan / kWh). Coal: advantages: low operating costs. Disadvantages: pollution, restrict the use of some areas, the cost of one ton of steam produced is about 150 yuan (coal prices by 900 yuan / ton).
Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam boiler for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.Free Chat
