Calculation of cooling area of sampling cooler

1: If the sample flow rate, cooling water temperature, and initial conditions of the sample are known, then the cooling surface required for the sampling cooler

The product can be obtained from equation (A1):

A=f ? 1.0029/3600 Δ Tm ? U (A1)

Equation - A - required cooling area, m2;

F - Sample flow rate, L/h;

Δ Tm - average temperature difference, ℃;

U - Overall heat exchange coefficient (U=200 for double-layer spiral tubes and immersion coolers).

When the sample is superheated steam, for every 100 ℃ superheat, the cooling area calculated by equation (A1) should be based on

On the basis of this, it will increase by 12.6%.

2: The average temperature difference can be obtained from equation (A2):

Δ Tm=[(t1-T2) - (t2-T1)]/[L (t1-T2)/(t2-T1)] (A2)

Equation-

Δ Tm - average temperature difference, ℃;

T1- cooler sample temperature, ℃;

T2- cooler sample temperature, ℃;

T1- cooler - cooling water temperature, ℃;

T2- Cooling water temperature at the outlet of the cooler, ℃.

3: The spiral tube of the cooler can be composed of a continuous coil with the required cooling area, or it can be arranged inside and outside of two sets of spiral tubes.

The purpose of fly ash sampler

The purpose and function of the fly ash sampler produced by Lianyungang Lingdong Electromechanical Equipment Co., Ltd. is that the carbon content of boiler fly ash is an important indicator reflecting the combustion rate of coal-fired boilers in thermal power plants.

Installation and working engineering of coal powder sampler

The installation and operation of the coal powder sampler and mobile coal powder sampler of Lianyungang Lingdong Electromechanical Equipment Co., Ltd. drill holes on the flue, extend the sampling tube into the flue, and make the sampling head face the direction of the incoming smoke flow.

Tube replacement of tubular oil cooler

When purchasing a column type oil cooler for tube and core replacement, the cooling area should be informed. The cooling forms are divided into LY type light tube (for use) and LYC type fin type. Stainless steel tubes are generally selected for heat exchange and cooling, and purple copper, brass, and titanium tubes can also be selected as heat exchange components according to user needs.

Steam -seal cooler

The role of a steam -seal cooler is to make the tram from the steam turbine slightly negative pressure, so that the auto continuously enters the auto seal cooler through the auto pipeline and condenses it into water for the boiler to use it.

Shaft seal cooler

The shaft seal cooler is used to extract the gas-liquid mixture from the steam seal system of the steam turbine, preventing steam from flowing from the end seal to the turbine room and oil system, thereby polluting the environment and damaging the oil quality. Generally, a shaft seal heater (shaft seal cooler) is used to heat condensate and recover shaft seal steam.

Replacing the tube of the shaft seal heater

Manufacturer of shaft seal heaters, also undertaking pipe replacement and renovation of shaft seal heaters, replacing copper pipes, stainless steel pipes, boiler pipes, etc. According to customer needs, the replacement, repair, installation, and restoration of the relevant shaft seal heater pipes must be carried out. The original equipment must be sent to our company for pipe bundle replacement.

Oil cooler tube replacement and maintenance

We are a manufacturer of oil cooler tube replacement and maintenance. We undertake various types of tube coolers, condensers, oil coolers, chillers, air coolers, condensers, and other heat exchange and cooling tube replacement and renovation projects. Change the material of the pipes, such as copper pipes, stainless steel pipes, titanium pipes, etc.

Replacing pipes for marine oil coolers

Welded steel pipes (also known as slotted pipes and welded pipes) are mainly used for auxiliary machinery in industries such as thermal power generation, chemical industry, and steel, such as condenser and heater pipe replacement, tubular marine oil cooler pipe replacement, oil-water cooler pipe replacement, tubular marine oil cooler pipe replacement, and Le tube cooler pipe replacement.

Assembly and installation of oil injectors

The oil supply and lubrication oil injectors are completely identical in structure, mainly composed of orifice nozzles, diffusion tubes, sleeves, filters, etc.

sampling cooler

Introduction to sampling coolers of soda: Solid sampling cooler is used for power plants, power stations, steel smelting, chemical, textiles, printing and dyeing and other boiler room furnace water and sampling cooler coolant. The sampling cooler can meet the standards of DL/T457-91 in the power industry , Met the sampling test requirements.
