Gas-fired 2010kg horizontal boilers supplier feed pump selection method! Water pump is the main equipment of gas-fired boiler, which is mainly used to replenish water of boiler to meet the normal water demand of boiler. The type selection of water pump mainly determines its flow rate and head. The specific introduction is as follows: 1, the flow calculation of feed pump: Q = k (Q1Q2): the flow rate of Q-boiler feed pump, m3 / h; Q1-Total water supply at maximum steam load for boilers, m3 / h; Q2-other water consumption, such as continuous discharge, periodic discharge and thermostat, m3 / h; k-standby factor 1. 1 ~ 1. 2.2, calculation of feed pump head of gas-fired boiler: h = H _ 1 H _ 2H _ 3H _ 4: h-boiler feed pump head, m; H _ 1-boiler opening pressure of safety valve under designed pressure, MPa; Resistance of H _ 2-economizer and water supply pipeline system, MPa; H _ 3-difference between the highest and lowest water levels of the water supply system, MPa; H _ 4 & mdash The other. 3, the gas-fired steam boiler feed pump shall be provided with a reserve, and when the maximum feed pump stops operating, the remaining total flow rate shall be able to meet 110% of the water supply required by all operating boilers at the rated evaporation capacity; When the boiler room is equipped with a dewarming device or a heat accumulator, the total flow rate of the feed pump shall be included in its water consumption. 4. One or more boilers with the same steam pressure may choose to operate side by side with two or more feedwater pumps, if the main pipe is used for water supply, Then you can choose two pumps and one backup, then frequency conversion water supply, which not only reduces the consumption of electric energy, but also makes the water supply pressure stable, although the one-time investment is relatively large. However, by means of frequency conversion and energy saving measures, the investment cost can be recovered in 3 years and 4 years. 5. Gas-fired steam boilers use steam-driven feedwater pumps as accident backup pumps. Its flow rate should be able to meet 20% ~ 40% of the water supply required by all operating boilers at rated evaporative capacity. Only when the boiler room with the first-class electric load and the feed pump stop running will not cause the boiler to be short of water, the steam-driven feed water pump may not be installed, and the non-power boiler room of the general industrial enterprise does not have such conditions, so it must be set up. Boiler selection has a direct impact on the boiler water supply system, it should be carefully selected.

March 26, 2018, fast Boiler Marketing Summit successfully held in Anyang, excellent strategic partner dealers across the country gathered in beautiful surroundings Huan Gulf Hotel venue center, witnessed ups and downs square almost 20 years, complicity future development plans.

Problems related to 2010kg horizontal boilers supplier hearth

The whole structure of boiler consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. Today, let's talk about the furnace of the boiler.
