Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.

Hot water boiler water filling boiler considerations and parameters between boiler pressure best price hot water boiler for sale of this kind in which the boiler is a common and frequently used species, but also in terms of all of us, need to have a comprehensive knowledge and understanding, because the only way to be correct and rational use of hot water boilers and have good results, but also to avoid misuse and adverse impact. 1. boiler parameters, whether on the same hot water boiler and steam boiler? From a professional point of view, the parameters of hot water boilers and steam boilers are not exactly the same, there are some differences, because the parameters of the boiler steam boiler steam boiler is concerned is the number of generated operating pressure and temperature steam, hot water thermal power boiler in terms refers to the boiler, the water supply and return water pressure and temperature. In addition, its different parameters, it corresponds to the unit is not the same. 2. Boiler Feed water pressure Cautions Boiler Feed pressure hot water process, there are some considerations, which is specifically as follows: (1) Sheung boiler heating system should be carried out separately, can not be together, because the boiler when you stop running between the boiler and the system is cut off. At the operational level, is you want to Sheung Shui to low water boiler expansion tank, then the system can Sheung Shui. Water Supply System, which can be used to perform Sheung pressure of the water filling the water system, if the pressure is less than water, circulating pumps can be used for water filling system. (2) If the system is filled with water by the circulation pump, which is specific to the operation: the boiler return pipe inlet valve is closed and the circulating pump will be multiplexed into the water pressure in the system until the system after the completion of charging water, then adjust the water level in the boiler. Meanwhile, while the system is filled with water, to be noted that the exhaust gas system. 3.1.4MV electric heating hot water boiler, heating area which is how much? 1.4MV electrically heated hot water boiler, its heating area is calculated, it needs to know the required heating power per square meter, heating, boiler pipes and boiler efficiency loss of these parameters, in order to obtain specific numerical values. If the heat required for heating power per square meter is 80W / h, boiler conduit 20% loss, then, the electrically heated hot water boiler heating area of ​​10,000 m2. However, this is the theoretical value, there may be some discrepancies with the actual value, without taking into account other external factors in this case.

Determine the location of the steam boiler room siting what issues need attention 1, boiler room refers to the building design boiler and ancillary equipment, water treatment facilities, pumps and sub-steam (water) tank and the like.

(2) Each steam boiler must have a reliable overpressure protection interlocking means interlock protection device and the low water level. (3) accessories and safety interlock protection device for each boiler to regular maintenance and testing to ensure that sensitive and reliable. (4) the building structure between the boiler should have the appropriate proof Measures. (5) operate independently of the fireman who must hold the appropriate level of operating permits fireman, boiler and continuous operation of the same class more than five years, has not been an accident. (6) There must be safe evacuation routes. 4, should not be located in the boiler room or a high-rise multi-story building basement, an intermediate floor or roof, but the conditions required setting time, shall meet the requirements of paragraph 3, the first gist of the present, should meet the following conditions, and former boiler room should be set prior consent districts of the city and over special equipment safety supervision agency: (1) steam boilers rated evaporation each no more than 4t / h, rated steam pressure does not exceed 1.6MPa; each heat rated water boiler (including direct fired absorption chiller-room unit) does not exceed the output of 2.8MW, the rated water temperature ≤95 ℃. (2) must be light oil, city gas, natural gas as fuel or electric heating boiler. Underground boiler room non LPG gaseous fuel or a density greater than 0.75. Connection (3) using a fuel supply pipe welding backing. In addition, when set in the basement boiler room, blowdown or appropriate measures should be set up sewage. When using gas as fuel, the exhaust system is also provided accident. 5, not connected to the boiler room A, (B) and (C) a liquid combustible fire risk room. If connected to other production plants, application firewall separated. Waste heat boiler is not so limited. Boiler production plant belongs to class D, between the fuel tank, between the pump delivery room Class C production, between the gas regulator belonging to the delivery room A of production. 6, between the outer wall or roof of the boiler should be at least equivalent to 10% of the area between the boiler pressure relief area (such as windows, skylights, shutters, etc.), and the relief port should avoid crowded places. 7, boiler room should be equipped with emergency lighting and evacuation signs, emergency lighting voltage shall not exceed 36V.
