oil and gas hot water boiler for hospital

Some small knowledge about oil and hot water boiler for hospital

Hot water boiler is one kind of boiler, mainly because its medium is hot water. There are many kinds of hot water boilers, which can be divided into point hot water boilers, oil hot water boilers, and some more environmentally friendly gas and coal fired hot water boilers according to the fuel used. The working principle of hot water boiler is very simple, which depends on the heat energy of fuel combustion to achieve the function of heating water, it is a kind of simple heat energy boiler.

Inner Mongolia Autonomous Region Development and Reform Commission issued a notice publicity Inner Mongolia clean heating in winter embodiment (hereinafter referred to as "Notice"), "notice" mentioned that in 2019 the region to achieve clean heating rate of 50% in 2021 to reach 705; urban built New forbidden zone 35 tons of steam / hour and below the coal-fired boilers, which Hohhot, Baotou, Wuhai city urban area will phase out 35 tons of steam / hour and below the coal-fired boilers, all new buildings to achieve clean heating.

The region's total heating area of ​​about one billion square meters of urban heating an area of ​​about 750 million square meters, of which: decentralized heating an area of ​​about 090 million square meters; central heating an area of ​​about 660 million square meters, heating rural area of ​​about 250 million square meters, of which central heating an area of ​​about 027 million square meters, the rest are dispersed heating.

Urban areas mainly in the CHP and district heating central heating boiler room mainly to gas, industrial waste heat, wind power, solar and other energy sources to supplement heating. Rural areas with decentralized heating the main heating source mainly scattered coal-fired boilers, conventional coal-fired furnace or straw.

Urban district heating cogeneration accounted for 51.5%, the proportion of area of ​​43.6% heating boiler, gas heating accounted for 4.5%, the proportion of the heat pump in other ways, electric heating and the like about 0.4%.

To clean as the goal, in ensuring the safety of people's livelihood heating premise, overall thermodynamic equilibrium between supply and demand, either alone or using a combination of various cleaning heating mode, alternative urban area and would like to keep burning coal for heating casual, less warm air pollutants areas emission. Adhere to safety bottom line, build a reasonable size, safety and reliability of heat supply systems.

2, according to local conditions, the residents can afford. Based on natural resources, economic strength, infrastructure around such as regulation and install air pollution control requirements, scientific assessment, depending on the region to its own characteristics, full old people's consumption capacity, adhere to both energy security and clean development, should power the electricity, should be coal is coal, the gas should be air, clean heating strategy adopted XI, to promote its low cost and low pollutant emission cleaning combination heating under the same conditions.

Considering the urgency of the air pollution control, affordability, work to promote the difficulty and other factors, co-ordinate the work of promoting cleaner heating city, county and urban-rural.

Safe use of chemical plant steam boilers and safe use of chemical plant maintenance measures and maintenance measures of a steam boiler, steam boiler how to prepare for chemical corrosion: preparedness, it is necessary to analyze the problem from the root, it is necessary to corrosion from steam boiler elements lead to corrosion of departure, to find a solution. In principle, resulting in steam boiler corrosion is an electrochemical corrosion. Boiler film surface layer of the electrolytic solution absorbs moisture in the air and CO2 constituted, or a metal surface composed of many small primary batteries many weakly acidic, neutral dissolution, iron as the anode, electrons are lost oxidized to Fe2 +, the positive electrode the oxygen dissolved in water to obtain an electron is restored. Corrosion biological structure is made loose, not diffusion barrier profile metal ion etching process will be performed successively. Second, how to deal with chemical steam boiler sewage: sewage is also considered an indicator of boiler steam boiler, now say environmental protection, environmental protection sewage to be called within a certain range. Sewage discharge steam boiler to do less ground row row, that is, the number of sewage to be more, but the amount of each drainage control in a small area, both to ensure that does not affect the steam supply, but also make pot of water quality has been in control It is within specifications, and a large shake does not occur, which is very beneficial for boiler maintenance. Third, the chemical plant steam boiler protection and maintenance: 1, the burner should be every two months removed from the boiler, careful eradicate coke dust and other foreign matter. Photocell light-receiving surface scrub once a month, to keep the fuel filter and clean the filter function; carefully clean the filter inside the oil pump, not to damage the gasket. Not oil-burner idle, to avoid damage to the pump. 2, the protective boiler maintenance, it is necessary to cut off the power supply, it is necessary to relieve pressure. 3, pulling the safety valve once a day, to prevent rusting failure. 4, the water level gauge should always be kept clean, flush purge valve open once a day, to ensure water clarity. 5, when the boiler suspend the operation time is longer, should cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt washed clean the furnace, slow fire the pot with a burner drying (combustion time not too long, to avoid damage to the boiler), and then after all the gas boiler drain, everything pipeline valves closed, to see once every three months. (2), wet maintenance for a period not exceed one month shutdown of the boiler, furnace shutdown after water release, discharge clean fill with water, cut off the power, close the valve. 4, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 5, the boiler stops longer running time, cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, slow fire the pot with a burner after drying (burn time not too long, to avoid damage to the boiler), then drain all of the gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve.

The control device talk boiler automation instruments in use in boilers, their controls automation instrument is extremely important, we are concerned that today. Evaporation of 4t / h and 4t / h boiler or less. Detecting water gauge, vapor pressure gauges, water pressure gauge, water thermometer, thermometer smoke, steam flow calculation. Oil temperature, oil pressure, oil level indication, computing fuel, furnace exit gas temperature indication. Boiler flue gas oxygen content should have, furnace pressure, economizer import and export water temperature indication. Or continuously adjusting the position feedwater automatic control, automatic adjustment of a combustion boiler burning heavy oil should be automatically adjusted, should there boiler pressure adjusted automatically. Alarm and protection. High and low water level indication and alarm, low water level limit protection, over-pressure steam indication, alarm and protection, flame protection furnace, fuel gas overpressure protection or low temperature alarm and protection. Auxiliary electrical control box, the boiler should be equipped with explosion-proof electrical control equipment. Programmable and others. Drums, Fan, and start and stop the pump interlock control program, drum, fan baffle opening damper indicated, shall be provided with explosion-gas boiler electrical control equipment.
