hot water gas condensing boiler
Comments about the hot water hot water condensing boiler structural principle: electric hot water boiler containing hot water boilers, hot water boiler fuel, gas hot water boilers and coal-fired hot water boilers, hot water boilers hot water boiler that is working is to use fuel burning release of thermal energy can heat or otherwise for heating water is heated to a temperature of additional tools. Natural circulation boiler water, inlet and outlet are on top of the receiving drum, the water is divided into water guide pipe and lowered into the front side lower header pipe, through the waterwall tubes into the heating rise. The front drum, and proceeds under reducing water impermeable liner is provided at the boundary, only the lower half of the impermeable plate spaced transverse to the drum.
Horizontal hot water hot water condensing boiler a few precautions, overpressure accident 1 boiler, steam boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" is still working pressure safety valve l high. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, steam boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
Gas hot water condensing boilers and oil-fired boilers and oil-fired boiler gas boiler difference is we will use in industrial boiler, although only one word, but what difference does it both? Xiao Bian today to introduce you to the difference between the gas boiler and boiler fuel: fuel oil-fired boiler is fuel such as diesel, oil, kerosene, fuel gas-fired boiler to gas such as natural gas, city gas, methane, etc., depending on the boiler fuel What devices called fuel burner, gas burner configuration called boiler gas boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners. Construction of boiler body is the same reason, need more thick steel plate with built-in boiler tubes are the same. The fuel gas boiler can be divided into natural gas, city gas, coke oven gas, liquefied petroleum gas and biogas, according to the function can be divided into water boilers, hot water boilers, heating stoves, heating stove, steam boilers, environmental protection boiler, bath boilers, bridge dedicated boiler, waste heat boiler, in accordance with the configuration it may be divided into vertical gas boiler, gas boiler horizontal; in accordance with the flue gas flow can be divided into three single backhaul backhaul gas boiler and gas boiler. Learn the difference between gas boilers and oil-fired boiler, I believe you must be the same as with Xiaobian learned a lot of knowledge, I hope this can help you better buy boiler equipment
The partnership, fast hot water condensing boiler for the user responsible attitude to have left a deep impression on our fireman boiler operation is not very skilled, fast deliberately sent a party of professional and technical personnel for our on-site supervision of installation, commissioning and training to ensure that the latter can operate our good boiler fireman. --customer feedback
