Features calcium carbide waste heat boiler during operation of the drum 1. The composition of operating pressures and gas turbine combined cycle steam boiler blowdown waste heat boiler has two or three drum, each drum minutes, run at different pressures, such as boilers combination of three steam drum, the drum has a pressure of a pressure drum, a low-pressure drum. In addition to the low pressure steam low pressure steam into the drum is not generated and the steam turbine into the deaerator, the high pressure steam supply to the steam drum Du machine. Qian any type of boiler, such as the presence or steam separator drum level fault, will produce serious chemical injury; for multi-component waste heat boiler drum, Q will be more serious. Further, in order to save water and energy transfer, sewage discharge way from the upper drum to the lower drum, and chemical changes affect the other drum in a steam drum. 2. Only water wall tube number 1 is set in the conventional exhaust heat recovery boiler waterwall tubes, the tubes can absorb heat due to the surrounding child, the cold side of the hot-side heat conditions conventional boiler waterwall tubes absent. On the other hand the flue gas flow, boiler, different heat flux and heat flux at the last row of finned tube of the first row at the finned tube, the difference was greater at startup. Typically, the first row of fins flue gas stream corresponds to the riser pipe, finned tube corresponds to the last row of the downcomer. However, the temperature rise in the boiler startup phase, as yet supplied to the steam turbine, the flue gas flow tuna rearmost tube sheet may be reversed, so that it corresponds to the initial rise in concentration of the chemical composition should be low, which allows the wall the resulting precipitate was minimal. 3. In addition to the waste heat boiler of the gas turbine combined cycle, oxygen is an important part of the low-pressure steam drum. Typically, low pressure steam into the low pressure steam generated by the drum deaerator feed water and makeup water to provide resources, as alternate start boiler is not provided, so that if the outlet steam pressure boiler system deaerator and the deaerator at start when open to the atmosphere, stop shutdown, the water tank to absorb oxygen, oxygen dissolved in water combined cycle heat recovery boiler causes pitting and fatigue corrosion. 4. The waste heat boiler because the DC current is no waste heat boiler drum, economizer nor evaporator superheater, when water flows through the tube bundle, the position of the interface is dependent on water vapor partial pressure of the water flow and heat absorption. 5. Run peaking gas turbine waste heat boiler can be designed to start and stop frequently, with a peak load operation, the situation in the future, peak load operation with frequent starts and stops often appear. But many ask the waste heat boiler with frequent stops the unit is related to the waste heat boiler difficult to adapt to frequent starts and stops with the state of the peak-load operation, the waste heat boiler operating status will cause a large thermal stress and chemical corrosion. These are the boiler equipment produced in the course of their work which reaction: inside equipment parts need to pay more attention, are carefully marked out.

How to siting the calcium carbide waste heat boiler room to install gas hot water boiler? When the gas boiler selection, will consider various factors, then a reasonable selection; but often do not notice the choice of location of the boiler room, in fact, the position of the boiler room will be related to the pre-investment costs, late operational management and security work, etc., is a rather important aspect. So how should be address to choose? (1) Gas boiler room so as not to set off in a crowded place too close to the area, in order to avoid noise in the boiler during operation or have other unforeseen circumstances affect human life and safety. (2) boiler room in most cases will be subject to various conditions, to be located in the basement of high-rise buildings and other places, then you should seek the consent of the relevant departments in advance, but it should also be noted that the choice of fuel and boiler rated evaporation and vapor pressure criteria defined in this state. (3) the location of the boiler room during the selection should be also taken into account the type of building, in the form of the system, operating pressures and other factors, to set up or normal operation of other facilities for the latter part of the pipeline, to lay a prerequisite. (4) should be close to the boiler room where the heat load more concentrated, in the tube grid, rational arrangement of the heat pipes to ensure economical and convenient. (5) in favor of natural ventilation and lighting, it should not be too confined space. In short boiler room location, taking into account the legitimate economic factors facilitate the safe operation of boiler standards, local conditions, etc., must not be selected without any planning, to the disadvantage of post-maintenance.

The cooperation with ZG calcium carbide waste heat boiler is a manufacturing company based in Malaysia that requires a steam boiler for production. Based on the customer's specific information and the specific needs of the customer, we have detailed the engineering plan for the customer and finally determined a 5 ton wns series gas steam boiler. This boiler has been carefully designed by our company's technical engineers to not only fully meet the customer's production needs, but also to optimize the use of benefits, cost of use (boiler fuel cost, boiler maintenance costs, boiler operating labor costs, etc.). Provide customers with the best solution.

Harbin Ecological Environment Agency announced plans to complete this year, Harbin more than 65 tons of steam coal-fired calcium carbide waste heat boiler soot ultra-low emissions and transform 140 units, ultra-low emissions of sulfur dioxide coordination to complete the transformation of 51 units, ultra-low emissions of nitrogen oxide transformation 20. Currently, the transformation plan has been, is being gradually start building renovation project.

Harbin nine districts built-up area and more than 65 tons of steam coal-fired boilers totaling 156 units, according to the national, provincial requirements, before the end of 2020 to complete the transformation of ultra-low emission. By the end of 2018, it has completed the transformation of ultra-low emissions to 16, and the remaining 140 units planned to complete the 2020 pre-season heating. This year's program priorities ultra-low emissions of soot complete transformation of 140 units, ultra-low emissions of sulfur dioxide coordination to complete the transformation of 51 units, ultra-low emissions of nitrogen oxide transformation 20; completed 2020 pre-season heating boilers remaining sulfur dioxide, nitrogen oxide pollutants over low-emission transformation. Up to now, the district had been held property unit boiler promotion meeting, 28 companies have 140 boiler by one to clear a specific time frame for completion and responsible persons, are gradually start building renovation project, planned before the end of September to complete the transformation of building construction; the end of October front, complete run debugging; before the end of December to complete the project acceptance.

It is understood, Harbin source of ambient air particulate matter analysis result display, the largest contribution to the PM10 and PM2.5 pollution sources are fired, share ratio of 31% and 36%, respectively. Ultra-low emissions of coal-fired boilers is mainly transformation soot particulate matter reducing emissions to the atmosphere, thereby reducing the concentration PM2.5, effectively improve air quality.
