Vaccum Gas Fired Hot Water Boiler


Vaccum Gas Fired Hot Water Boiler

The main problems of autonomous decentralized boiler heating mode: 1, "two small" boiler room that is small-scale (10,000 m- for the following boilers 60%), small boiler capacity (single boiler average capacity of only 2 tons / hour). "Two low", i.e. the boiler load is low, the thermal efficiency is low. Calculated heat index 70W / m =, 0.7KW (i.e. 1t / n) for 10000m =, in fact, only for 4000m =, less than half, in the "Mara car" low load operation. Thermal efficiency is naturally low, generally only reach 50-60% oC "two can" That is more than the energy consumption, the existing multi-intermittent heating (burning six hours every day and night, stopping six hours, repeated twice). In the current institutional heating intermittent heating accounted for 82%, only 18% of continuous heating. 2, boiler room hire older workers and the burning of a modern boiler during operation merely by virtue of the experience "the sky light a fire," there is no scientific basis for heating, that is, how many points you cold, warm day less burning point, which is very difficult to achieve the purpose of heating and energy requirements. 3, the heating system is unreasonable, due to some historical reasons causing heating in the system has inherent missing, and in the intermittent heating is due to habits die hard so the resulting decline in the quality of heating also a waste of energy. 4, which is related to the owners and the quality of that set out secretly put a hot water tank, can lead to heat loss, water loss occurs, really makes the heating unit is really a headache, which cause heating problems. 5, since the local heating technology of high and low level, so that in the heating process, the heating requirements for the simple pursuit of the distal end of the owner excessively coal temperature of the heating water, resulting in overheating proximal end, a distal end of the warm unbalance, or warm proximal distal cold conditions, which resulted in a waste of energy, will not help solve the problem. 6, the boiler disrepair, will take place at the junction of the pipeline corrosion, fouling and even the phenomenon is really due to the HVAC heating during water treatment errors caused by, resulting in fouling of the boiler heating surface, or Since the agent is such that the boiler ash surface to form grime, which is management problems. 7, the high heat load design makes enormous waste in financial resources, but also makes the device parameter selection is also too large, the most important thing is a waste of energy. 8, due to improper selection of the boiler supply pump, such that the heat medium low boiler room parameters, the performance of the boiler is low lift, low thermal conductivity, insufficient heating vicious circle. 9, due to the design of overkill situation arise, ie, a single heating boiler can solve the problem, but using a more common heating boiler, resulting in low thermal efficiency of large coal consumption and generate unreasonable conditions. 10 vertical imbalance, if indoor heating system will be conducive to eliminating the balance of water resistance, which requires the designer to identify line) inputs the number of circulating pump is too large, such a large pump flow, low return temperatures, generally in 25 degree. This will increase electricity consumption. 11, about the nature of different heating buildings, commercial buildings and residential buildings if the use of a heating system is the same, then since the days of the commercial building heating requirements of large, large civil construction heating at night, if you can not time-heating, is bound to cause waste of energy. 12, single-tube heating system installed can not be achieved thermostatic valve on the radiator, but now a lot of indoor heating systems or belong to single-tube system, which is not conducive to long-term development. 161, why gas hot water heating boiler heating problems occur each year to slow the heating time, a gas boiler heating the user of the problem in many areas of heating will slow, but the problem is often not the fault based on the boiler itself. In this regard, today we elaborate on the reasons for this phenomenon. 1, because the use of gas-fired boiler heating, after carrying out the heating boiler ignition, but also need to go through the oven, cool-running, heat exchangers and other process, so as to make heating gradually warming. After the gas vaccum fired hot water boiler heating during ignition, the oven is ready to work early each year heating must be carried out, a process that takes about 3-5 days to complete. 2, the use of the process, gas hot water boiler also need to go through the process of heat transfer, the temperature will gradually rise. Gas heating boiler heat exchange process is mainly water cycle process, stand out from the hot water not flow directly to the residents of the home heating network, but need heat exchanger unit to transfer heat energy in the hot water heating plant to the residents of the home in the circulating pipe network. 3, starting at the initial stage of the heating boiler, water temperatures of the respective heating stations is not very high, coupled with the complex structure of the network, the gas hot water boiler heating hot water heat exchanger is a process, especially in the end of the pipe network user, heat transfer process will be a little longer time.

Principles of steam boilers and solutions hydraulic external gear: told you about the principles of steam boilers and solutions for steam boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil steam boiler, gas steam boiler three kinds; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, a large steam boiler plurality of three-pass horizontal structure. If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories.

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. Boiler should be separate and independent from other buildings. Boiler room should not be set directly in crowded places (such as public bathrooms, classrooms, restaurants, auditoriums, shopping malls, waiting rooms, etc.), or at the top, bottom, or the immediate neighborhood of the main evacuation port on both sides. 2, the new boiler room should not be connected to the house. 3, provided in the boiler room such as a semi basement layers or high buildings or the first layer must meet the following conditions: (1) each steam boiler rated evaporation does not exceed 10t / h, steam pressure does not exceed the rated 1.6MPa; rated each water boiler (including direct fired absorption chiller-room unit) does not exceed the output 7MW, the rated water temperature ≤95 ℃. (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.

Around the low nitrogen emissions and thermal efficiency of the boiler regard, Jiang Zuojun, who are very interested in the company's showroom will watch the animated presentation, could not help nodding in approval, other fast boiler in a variety of achievements in the industry made a lot of money and gave high praise and affirmation. Subsequently, a pedestrian visited the lab to clean the boiler group, for the constitution and the implementation of the Group's research laboratory work was questioned and understanding.
