Valve Solutions for Pulp & Paper Applications 97.01-01
BULLETIN 97.01-01 MAY 2021 VALVE SOLUTIONS FOR THE PULP & PAPER INDUSTRY The DeZURIK Difference Throughout our 250 years of combined history, DeZURIK, APCO, and HILTON have been recognized worldwide for collaborating with customers to design and engineer valves that provide superior performance and value. Each company was founded by an innovator who set out to solve a customer’s problem application. DeZURIK’s founder, Matt DeZURIK, started designing products for the Sartell Paper Mill in 1925 that included knot boring machines, consistency transmitters and shower pipes. When he noticed that valves weren’t able to seal due to pitch build-up, he invented the first Eccentric Plug Valve – a design still in use today, dutifully solving sealing problems worldwide. Today, the DeZURIK, APCO, and HILTON brands continue the tradition of partnering with our customers in the Pulp & Paper industry to provide the newest innovations in control, gate, plug, butterfly, automatic air and check DeZURIK’s original Eccentric Plug valves. Our vision is to deliver exceptional value to our customers Valve, developed in 1925 for the Sartell Paper Mill to solve a problem by applying our valve and problem-solving expertise to improve their with pitch build-up. operational performance. Full-Featured Valves for Today Applications DeZURIK recognizes the importance that control valves can play in process control performance and productivity. That’s why DeZURIK is dedicated to control valve testing. Regulating critical aspects of control valve performance such as accuracy, hysteresis, deadband and response time ensures that DeZURIK control valves provide optimum performance and help reduce costs. DeZURIK Knife Gate Valves and V-Port Ball Valves are widely used in pulping and stock prep operations throughout the mill. -

ENGINE COOLING and VEHICLE AIR CONDITIONING AGRICULTURAL and CONSTRUCTION VEHICLES What Is Thermal Management?
ENGINE COOLING AND VEHICLE AIR CONDITIONING AGRICULTURAL AND CONSTRUCTION VEHICLES What is thermal management? Modern thermal management encompasses the areas of engine cooling and vehicle air conditioning. In addition to ensuring an optimum engine temperature in all operating states, the main tasks include heating and cooling of the vehicle cabin. However, these two areas should not be considered in isolation. One unit is often formed from components of these two assemblies which influence one another reciprocally. All components used must therefore be as compatible as possible to ensure effective and efficient thermal management. In this brochure, we would like to present you with an overview of our modern air-conditioning systems and also the technology behind them. We not only present the principle of operation, we also examine causes of failure, diagnosis options and special features.

Using Radiators with Wetback Fires the Joy of Fire with the Comfort of Central Heating
using radiators with wetback fires The joy of fire with the comfort of central heating. Heating Radiators with Fire Log burners are commonly available with a wetback system that heats • Heat more of your home with a hot water cylinder. It’s possible to extend the functionality of the your fire wetback by using radiators to spread the heat to other parts of the house. • Radiators available in a This means you can get the pleasure of watching a fire burn in your living variety of styles and endless room while the rest of the home is brought to a comfortable temperature colour options by the radiators. • Using a cheap and reliable People often try to move the hot air from a fire into other parts of the source of firewood means no house with duct work. Moving heat with water is so much more effective additional fuel costs as water transports energy four times better than air. The number of radiators you can heat depends on the heat output of the wetback and the rating of the radiators. A typical wetback only provides 2 to 4kW of heat as this is all that is needed to heat a hot water cylinder if the fire is on for five to ten hours per day. In order to heat a central heating system, a wetback with a higher output is often required. There are fires that have larger wetbacks (up to 15kW) and put out more heat to the wetback, enabling more radiators to be connected. How It Works While the fire is burning, the heat from the combustion process heats water jackets installed within the firebox. -

The heat transfer surface of this heat exchanger is composed of polymeric hollow fibers made from polyamide 612 by DuPont (Zytel LC6159). The cross-section of the polymeric radiator is identical to the aluminum radiator (louvered fins on flat tubes) in a Skoda Octavia and measures 720 × 480 mm. The goal of the study is to compare the functionality and performance parameters of both radiators based on the results of tests in a calibrated air wind tunnel. During testing, both heat exchangers were tested in conventional conditions used for car radiators with different air flow and coolant (50% ethylene glycol) rates. The polymeric hollow fiber heat exchanger demonstrated about 20% higher thermal performance for the same air flow.

Heat Transfer and Cooling Techniques at Low Temperature
Heat Transfer and Cooling Techniques at Low Temperature B. Baudouy1 CEA Saclay, France Abstract The first part of this chapter gives an introduction to heat transfer and cooling techniques at low temperature. We review the fundamental laws of heat transfer (conduction, convection and radiation) and give useful data specific to cryogenic conditions (thermal contact resistance, total emissivity of materials and heat transfer correlation in forced or boiling flow for example) used in the design of cooling systems. In the second part, we review the main cooling techniques at low temperature, with or without cryogen, from the simplest ones (bath cooling) to the ones involving the use of cryocoolers without forgetting the cooling flow techniques. Keywords: heat-transfer, cooling techniques, low-temperature, cryogen. 1 Introduction Maintaining a system at a temperature much lower than room temperature implies that the design of your cooling system must ensure its thermal stability in the steady-state regime; that is, the temperature of your system must remain constant in the nominal working condition. It also requires a certain level of thermal protection against transient events; that is, your temperature system must stay below a certain value to avoid problematic situations such as extra mechanical constraints due to the thermal expansion of materials with temperature. The ultimate goal is to minimize the heat load from the surroundings and to maximize the heat transfer with a cooling device. To be able to achieve this objective, identification of the different heat loads on the system is required, as well as knowledge of the fundamental laws of heat transfer, the thermo-physical properties of materials and fluids such as the density (kg·m–3) and heat capacity (J·kg–1·K –1), and thermal conductivity (W·m–1·K–1) and the cooling techniques such as conduction, radiation or forced flow based techniques. -
