The water circulation of the vertical drum (and KB-shaped) water tube boiler is divided into two parts: one part is that the water of the upper drum is lowered from the weaker convection tube bundle at the rear to the lower drum, and then the front part of the lower drum is heated more strongly. The convection tube bundle rises and returns to the upper drum to form a circulation; the other part is that the water of the water wall tube around the furnace rises to the upper drum, and the descending pipe drawn from the lower drum supplies water to the water wall pipe through the headers to form a water circulation.
Gas-fired steam boilers dominate the boiler industry by saving energy, environmental protection and durability. Through advanced scientific and technological improvement, energy conservation and emission reduction have been improved. And domestic professional gas-fired steam boiler not only improves the heat absorption strength of the boiler, but also satisfies the demand of thermal expansion on the hot surface. The specific reasons why gas-fired steam boilers are popular with users can be found in the following sections:
1: the use of cleaner gas-fired steam boilers with a more environmentally friendly environment in use, the reputation of natural gas as a "clean fuel" and the absence of harmful gases and dust from the combustion process, Therefore, there will be no pollution burden on the air and the environment. Carbon dioxide or smoke produced by traditional coal-fired boilers not only affects air quality but also affects physical and mental health. Therefore, the use of gas-fired steam boilers is environmentally friendly.
2: the thermal efficiency reaction of a gas-fired steam boiler with high thermal efficiency is relatively faster than that of other boilers because it uses pure natural non-polluting natural gas as a combustion fuel with high thermal energy. The fire stimulates the rapid conversion of heat and causes water to release steam continuously in the pot. Compared with other coal-fired and fuel-fired boilers, the thermal efficiency is the fastest and most effective.
3: more intelligent operation of gas-fired steam boiler does not require manual complex operation of the whole process using intelligent automatic control. All working processes can be easily used by setting all the parameters in advance. Gas-fired steam boiler can start and stop automatically and automatically adjust the load to feed water according to the requirements of user design. Any abnormalities during operation can also enable self-diagnostic interruptions to fire an acousto-optic alarm.
First, check whether the diameter in claim boiler pressure china horizontal hot water boiler for sale is the same as the opening to the atmosphere, under any operating conditions, the water level in the boiler are zero gauge pressure boiler. Therefore, before use, the user should check for new boilers, in particular, check whether the diameter to meet the requirements. Further, the communication tube should be prohibited in any valve provided to ensure smooth takeover. Generally, professional supply of pressure hot water boiler will spray "pressure boilers may not use pressure and hot water outlet temperature should not exceed 90 ℃" warning labels in the apparent position of the furnace. Second, installed by professionals, debugging initial purchase use, pressure hot water boiler manufacturer will recommend the installation and commissioning of the boiler by professionals to be responsible. Once operational, non-professionals are not allowed to change the structure of the boiler, free installation system piping, valves. At the same time, it should also be noted that must not be converted boiler pressure hot water boiler pressure. Third, to ensure that sensitive and reliable boiler safety accessories
To comprehensively promote the prevention of air pollution control work, steadily enhance the quality of atmospheric environment, located in the northern part of Heilongjiang Province held a mobilization meeting Sunwu out of small coal-fired boilers to May 7.
Conference announced the "2019 Sunwu urban area out of 10 tons of steam per hour and coal-fired boiler embodiment."
To promote the elimination of built-up area of small coal-fired boiler work, the relevant departments should strictly follow the higher level requirements, the investigation to find out the use of coal-fired boilers and urban planning area of built-up areas, with their own reality, do a good job to implement; should attach great importance to raise awareness, according to the embodiment and objectives, and take various measures to actively promote the complete phase-out of coal-fired boilers small task; to actively publicize the relevant policies, regulations and requirements to the boiler owners, guided by the responsibility to implement, clear time node . To seek truth from facts, objective science, policy guidance, strict enforcement of the principle, in order to reduce air pollution, improve air quality and protect people's health as the goal, according to the classification regulation, departmental interaction, Duocuobingju, the overall advancement of the process steps to form a government command , business differentiation, market-driven, effective supervision, public participation in new air pollution control mechanisms, to promote the phase-out of coal-fired boilers built-up urban area.Free Chat
